When you forward messages, the signature line is added at the bottom of all
messages forwarded. I would like to be able to configure the mail editor so the
signature line appears before the messages being forwarded and after the new
text entered. In other words, I would like the placement of the signature line
in forwarding messages to behave identically to the manner in which it behaves
when you reply to a message.
Reproducible: Always
Steps to Reproduce:
1. Configure system to insert a signature line
2. Forward a message
Not a preferences dialog issue..

Honour the place-signature-above-reply setting when forwarding mails.
This is the same as #214514, which was perhaps incorrectly flagged as a dup of
the #62429 uberbug. It's a quirk that i've constantly had complaints about,
and attached is a simple patch to compose/src/nsMsgCompose.cpp which fixes it.
Hopefully replacing the htmlEditor->RebuildDocumentFromSource(aBuf) with
htmlEditor->insertHTML(aBuf) doesn't clobber any edge cases I'm unaware of...
Removing "DUPEME" -- I believe Matthew has ID'd the potential dupe.

Sorry, I am new at this. I see your patch from August, but that means I have to re-compile the source myself right or is there a binary available already somewhere else? Why was your patch not included in the more recent release of Thunderbird? Thanks Mike/Matthew.
The patch is flagged for review, but currently is still waiting in mscott's queue. Depending on what areas of code a patch affects, and the status of the product, patches may need a review, super-review, and approval marking before being checked into the code. Once checked in a fixed binary will be available as a trunk nightly; it may be a while before a officially released version includes the fix. Of course, this process moves quicker for security and crash bugs versus enhancements.
Do anyone know of an existing Extension that would work in the interim?
nope, that's why I wrote the patch :( Your only chance for now is to build your own custom build of Thunderbird (which takes a few hours of setup, and a few hours of compiling, assuming nothing goes awry).
*** Bug 349269 has been marked as a duplicate of this bug. ***
This is to basic, please make it a part of Thunderbird 2.0 !
I like Thunderbird very much, but this is for me the most annoying "bug" of Thunderbird.
Especially if the messages are longer I always have to go to the bottom and cut & past the signature to the place under my text and above the old messages as would happen with "reply".

unbitrotted patch
I was trying this out. The patch had bitrotted so here should be a version applying to trunk.
I notice the "-- " delimiter is still there when putting the signature on top. (It shouldn't.)
But then again, I'm not sure this is functionality I would like. Maybe it should be a pref of it's own, not connected to replies. (Or no sig at all for fwd, bug 167319)
Does this patch get applied if body text is passed in from an external source?
Such as Send Link from Firefox, or a mailto: with a body argument? I'm just not sure what situations lead to 'aBuf' containing content.
I like the idea of not adding sig at all for (inline) forward, but if that were made the only possibility, there's sure to be a load of complaints.
Yeah... seems like the htmlEditor->InsertHTML(aBuf); line should go. (Didn't test though.)
Is there any other way around this 'signature below rather than above' issue outside of recompiling? (I have no idea how to recompile).
I'm an end user that cuts and pastes his signature from below to above during many forwarded e-mails to clients. This would be an incredibly logical and efficient feature/bug fix.
Any information on the status of this would be greatly appreciated. Thank you very much for your time and efforts.
I cannot believe that my first post about this issue (in the forums) was in 2005 and yet it still has not been resolved. I even posted to this bugzilla report 1.5 years ago (see above) and the patched .cpp fix still hasn't made it to the releases. Other than the endless/useless "top-posting vs bottom-posting" debate, what is the hold up for making this an OPTION or at least someone creating an extension for it???
On that note, knowing nothing about creating extensions (but having done some programming in university), if I were to try to make one myself is it possible, or would it be overly difficult to do so for this issue? Thanks.
Has anyone compiled there own release of 2.0 with this fix. If you have can you email me?
Any news? I've hordes of users aiming at my throat for this. A few bosses already went back to Outlook :(
check this out
That doesn't address this problem. Signature still appears at the bottom and I don't have the Signature Switch addon. It's really just a matter of the Tbird developers not wanting to include something they feel is a microsoft violation of "traditional practices" (notice I didn't say standard - there's no actual RFC for this). Or, simply put, pride. Heck, I can't even get someone to help me with an extension for it. The lesson here is that Open-Source does not necessarily mean Open to Ideas. But that debate is for the forums - just wait it out, they'll come around.
tested with 188.8.131.52 But the problem is still there
I was wondering if there was any way that someone like myself (who is quite computer literate, but not a programmer) could fix this signature problem without spending hours compiling and recompiling?
Does anybody know if and or when this problem might be resolved?
Thank you for your time.
I initially reported this problem in December of 2004. I just installed Tbird version 188.8.131.52 and the problem is still there. Is there any hope of getting this annoying problem fixed before we hit the third anniversary of my reporting the problem?
I have just upgraded to 126.96.36.199 (20070728)and hoped that the signature placement problem was fixed. It takes up an enormous amount of my time cut and pasting my signature " below my reply (above the quote)". And often it doesn't want to paste it. This is my only complaint/irritation with Thunderbird. Please will you fix it asap. I have fixed signature placement on replies. If anyone can help me with a fix for forwards, I would really appreciate it. Thank you, Robin
I wholeheartedly agree. I absolutely love Mozilla Thunderbird and have been using it for years. This "cut-and-paste" of the e-mail signature when forwarding, which, as Robin mentioned, usually doesn't work, is a real annoyance.
I wish the problem could be resolved. And I know that this flies in the face of open-source-ness, but I offer to donate to the person who gets this solved. Just name your price. I'll donate half to the Mozilla Project and the other half to the person or persons who gets this solved.
At times like these, I wish I were a programmer.

Actually, it doesn't fly in the face of open source at all! Programmers donate their time (time=money) to projects to create something they would like. You (not being a programmer) donate your money to (in the end) create something that you would like.
In the end, everyone benefits.
I remember seeing some website where you could put what you wanted coded and how much you were willing to pledge (other people could jump on the bandwagon to add to the amount) and then a coder would take the project and get paid when it was complete. I'm sorry I don't remember where it was exactly -- perhaps someone could help me out there?
This feature is dearly wanted here too ! I am refreshing the patch for the current trunk (almost trivial in fact, I am spending most of the time compiling for both Linux and Windows), an I should be publishing the patch shortly to keep it fresh, but it seems a good thing to push this bug as it is a user-desired feature.
I would like to reiterate that I will pay for this signature problem to be resolved as it will save me much time and unnecessary annoyance.
What can we do to move this process along?
I will refresh the patch (done), test it (underway) and then publish it (ASAP) and this should refresh the attention on this bug.
The French Ministry of Finance is expecting integration of this bug too. Hopefully this makes 2 big sets of users waiting for a good end on this bug, you may end up not needing to pay for it.
I think I'd really prefer it to be a pref of it's own, not connected to replies. Which should also handle the no at all for fwd, bug 167319.

First, this is the same patch that is already attached to this bug. It also have at least two flaws (see comment 13 to 15).
When you have a patch ready for review, set the r? flag of the attachment to the e-mail of a suitable reviewer to ask review. r+ says the patch was reviewed and ok. You also need superreview.
As this isn't something that would go into the tb2 security releases, please make the patch against CVS trunk.

This patch does not apply, i'm not sure to what version it was supposed to apply to either, but there is no need to post patches for anything but current cvs trunk before you have a patch that has been reviewed and checked in there.
I really think bug 167319 would be the way to go though, combined with the option to choose before or after the quoted message. The setting should be independent and not tied to replies. I know I never forward stuff to people who I don't know (and thus have no use of my sig).
Well, as for the version aginst which it applies :
--- mailnews/compose/src/nsMsgCompose.cpp 28 Jan 2008 16:51:42 -0000 1.546
+++ mailnews/compose/src/nsMsgCompose.cpp 7 Feb 2008 09:10:00 -0000
...not too old, is it ?
Anyway, you're fundamentally right - forward is a pretty special case.
I suggest one thing : just tell me on which version you'd be reading and let me provide the patch for you. The behaviour is pretty simple, I just add the boolean addDashes according to what I want, plus the original ported patch.
Didn't check what the problem was, but at least one HUNK failed when trying to applying one of the patches, and the other applied but didn't compile due to the docshell stuff.
Latest cvs version please:)
I only officially review /mail code, try one of the Mail and News Backend peers, http://www.mozilla.org/owners.html for a real review.
I am perfectly ready to do as much as possible, but you will realize that I am no more willing to port the patch on many versions, as well as you are not willing to patch it yourself. What we've learnt from this is that the target file, nsMsgCompose.cpp, seems to be under heavy patching. What I can do is to port the patch to today's trunc, then warn me as you read it so I make sure the patch is up to date and update one, obsolete the other at will. CVS provides some help with patching but it is sometimes just not enough, and we both don't want such an unpleasant surprise to happen again, so go for it ?
I make sure the patch gets up to date for today, 16.00 CET, and I ask you to warn me if you want to read it, so I check no update breaks the patched file, OK ?
Thanks in advance, and feel free to use my personal mail if appropriate.
Well, the relevant file has been committed thrice since the patch, hence the problem... I make the patch up to date.

*** Bug 418820 has been marked as a duplicate of this bug. ***
I'm not sure what this "patch" does, but I am hoping it adds another line to the configuration where instead of "Automatically quote the original message when replying", it says "Automatically quote the original message when forwarding" and has the same settings for this function.
And shouldn't the "Version" here be "2.0" or "branch" instead of or in addition to "Trunk"? This is a low profile, high gain bug, and should have the following keywords: "mail6:Low risk, high gain Mail bugs. Mail Bugs which require little engineering effort but have high user benefit that might not otherwise be covered under the other keywords." "ue:For bugs with a specific detailed suggestion for improvement of the user experience. The problem describes a confusing or unhelpful aspect of the user interface."
(In reply to comment #62)
Doesn't change quoting, just puts the signature in the above the original message if reply-settings is "above".
There is no point playing with keywords, the mailX ones I understand were used - by developers - way back in the netscape era for prioritizing, especially as we already have a patch. Nowadays they really shouldn't be used imo, since it doesn't make sense that anyone can add them (at least to their own bugs).
No, Worcester12345, I did add no configuration element, all I did was keeping in sync with the use : ie signature delimiter only when the signature is at the end of the messsage.
I am ready to discuss this point, but I do beleive that adding yet another configuration element might be too much.
There is no need for a new configuration element, please fix this bug fast, it would be nice to have it in TB 2.0013 release, thanks !!!
I think it is more importent to make it work then long talks.
A new configuration element can wait for TB 3, this is a bug there gives a lot of problems so make is work with the setting for replaying messages and thats it.
Michael, IMHO it is *actually fixed* by the patch enclosed first, which I just improved in the main sense that was asked for by the replies here (the remark #13 has been taken into account, Magnus could check, see #57).
What leavs to be done is the configuration element, but I do not yet know how to add one, this could take some time for me. Either include it temporarily with reserve or have it done if you want it for 2.0013, but I can't guarantee I'll meet the deadline !
Benoit, I understand your problem and I hope some one can help you with that, but this is a bug that never should have been. In all e-mail clients this is stand, so that way I think this need to be done fast.
Is there some of det other developers there can help to get this done ?
If this is not the case, can your fix use the settings form the configaration element for replaying messages ? If so I think that the way to go.
It is what it already does, and what the initial patch has been doing for ages (almost 3 years...). What I did was simply the "-- " handling trick, ie no signature delimiter when the signature is placed before the reply.
As for a bug that should never have been, well, this behaviour goes simply against RFC1855... However I understand and find top-quoting quite convenient and productive myself.
An enhancement request isn't going to "block" a release, but if the mail owners are happy with a small, safe, patch you can request approval on it. The fact that the mail owner hasn't reviewed the patch in over a month is not a great sign, however.
Well, I haven't set the flag myself, but well, I wonder if I should flag it as FIXED so as to ring a bell to the supposed reviewer... Well, I begin with a proper assignment and see the rest.
Well, who should set the bug "Fixed", the reviewer ? If yes, then please anyone to review ? I'd be ready to discuss the final "how" if there needs to be one, but some people are waiting this fix for so long...
The patch looks basically reasonable.
+ if (sigOnTop && !aSignature.IsEmpty()) {
+ textEditor->InsertText(aSignature);
+ m_editor->EndOfDocument();
+ }
Could you fix the braces style to match the rest of the file, i.e.,
if (a)
/* Some time we want to add a signature and sometime we wont. Let's figure that now...*/
PRBool addSignature;
+ PRBool addDashes;
It seems like it would be cleaner to initialize addDashes to PR_FALSE so you don't need to set it to FALSE in three different places. Or,
PRBool addDashes = (mType == nsIMsgCompType::ForwardInline);
I haven't tested the patch; Does it apply, or do you need to update it to make it apply? In either case, if you could submit a new patch with my comments addressed, I can give it a try.
(You don't mark a bug fixed to bring attention to it; We mark it fixed when the patch is checked in)

I'm happy with the code in this patch.
The only thing I'm not sure about is not having the dashes before the signature. I'm not saying I disagree, I'm just not sure what should happen, and I know Bryan has had discussions on this recently. Therefore requesting his ui-review to check this is what we want to do.
As with most things concerning signatures, people will likely get upset whatever you do... :) You can literally spend a day reading just a couple bugs where the signature options got implemented.
Having "-- " above would cause severe flaming, but i wonder if we couldn't instead use "--" for top posting and visual consistency. (Though I don't think this is the bug to do that.)

Yeah. ;-)

But deliberately introducing a broken signature delimiter would be just bad.
> But deliberately introducing a broken signature delimiter would be just bad.
Heh, but it wouldn't be a signature delimiter then would it? ;)
My understanding, after spending a couple days reading all those signature bugs, is that if we add the "-- " to a signature above an inline message forward thunderbird will render everything below that signature delimiter as part of the signature (bug 54570).
Alternatively the current behavior always inserts this "-- " delimiter above all signatures so we could maintain consistency by continuing in that path.
My recommendation in bug 58406 was to use the delimiter by default, but not require it. But that recommendation would likely still create the render problem.
I would exclude the "-- " and not include anything else. If bug 54570 is fixed before bug 58406 gets fixed there shouldn't be a problem.
Bryan: the patch does that - exclude the "-- " and not include anything else. (Just does the same thing as what we currently do for replies.)
Did you mean to mark it ui‑review+

It's just fixed for thunderbird3 (and nightly builds). In general, 2.0.0.x just get security and crash fixes.
This is a big bug, and it would make a lot of sense to go above and beyond and include the code for the current shipping branch.

Still running into issues with this problem. Is there any way that this can now be landed on branch builds, since it has had a chance to "bake" on trunk builds?
Not blocking a security branch release. If the mail module owners want they could back-port the patch and ask for branch approval for the next release (today is code freeze for 184.108.40.206 so it's not making that one).

TeenHealthFX understands that moving can be a difficult transition - especially when you move to a new country and are feeling far from your friends and culture. For many people a move like that can be a really tough transition, but at your age, it can be particularly hard since your friends no doubt play such an important role in your life. As impossible as it may seem, making new friends will happen in time. But before you can look to your peers for acceptance, you have to find a way to accept yourself.
Maybe talking to a therapist would be helpful for you. If deep down you feel every person is better than you, then your life is bound to be full of disappointments.

Teens often abuse prescription drugs because of the myth that these drugs provide a medically safe high.
It is estimated that major depressive disorder (MDD) affects about 5% of adolescents, and that between 10 - 15% of adolescents have some symptoms of depression at any one time.
Statistics show that giving a teen a credit card does not teach them to be financially responsible or to encourage self-restraint, but actually promotes a "spend now and deal with the consequences later" mindset.
Girls are more likely to intentionally abuse prescription drugs than boys.
The reality of excessive interest rates and fees that often accompany credit card use for teens, can put youngsters in a position where they are losing out on admission to graduate school, getting a job, or renting an apartment because of damaged credit history.
Less than 33% of teens with depression get help, yet 80% of teens with depression can be successfully treated if they seek help from a doctor or therapist.
Traffic crashes are the greatest single cause of death for all persons age 6-33, and about 45% of these fatalities are alcohol-related crashes.
About 6.2 million Americans get a new genital HPV infection each year.
30% of teens with depression also have a substance abuse problem.
Freshmen bring an average of $1,585.00 in credit card debt to college.
About a third of women who seek services related to unprotected sex, such as pregnancy testing or emergency contraception, do not receive STD counseling, testing, or treatment.
7-10% of college students will drop out of school because of credit problems.
Teens with untreated depression are more likely to engage in risky sexual behaviors, leading to higher rates of teen pregnancy and sexually transmitted diseases.
Most smokers begin smoking as teens, and the average age of initiation is 12.5 years of age.
People with manic symptoms and Bipolar Disorder II are at a significant risk of later developing an alcohol abuse or dependence problem.
Motor vehicle crashes are the leading cause of death for U.S. teens, accounting for 36% of all deaths in this age group.
The teen pregnancy rate in the United States is the highest of any industrialized democracy, nearly twice that of Great Britain and 10 times that of Japan. 4
Compared with other age groups, teens have the lowest rate of seat belt use, and male high school students are more likely than female students to rarely or never wear seat belts.
A national study of women ages 15-44 found that women were almost twice as likely to receive contraceptive services rather than STD services.
The teenage pregnancy rate in the U.S. is at its lowest level in thirty years, down 36% since its peak in 1990. Research suggests that both increased abstinence and positive changes in contraceptive practice are responsible these recent declines in teen pregnancy.
A sexually active teenager who does not use contraceptives has a 90% chance of becoming pregnant within one year. 8
In the United States, at least 5-10 million girls and women and 1 million boys and men are struggling with eating disorders. 11
Among male drivers between 15 and 20 years of age who were involved in fatal crashes in 2005, 38% were speeding at the time of the crash and 24% had been drinking.
Homicide is the second leading cause of death among 15- to 24-year-olds overall. 16
Every two minutes, somewhere in America, someone is sexually assaulted. 22
One in four teenage girls in the U.S. had at least one common sexually transmitted disease.
Suicide is the third leading cause of death among youths ages 15 to 20. 19
The highest Chlamydia rates occurred among women ages 15 to 19 and 20 to 24.
About 44% of rape victims are under age 18. Three out of every twenty victims (15%) are under age 12. 25
Each year, half of all HIV infections are among people under the age of 25.
Crash risk is particularly high during the first year that teenagers are eligible to drive.
One out of every six American women have been the victims of an attempted or completed rape in their lifetime. A total of 17.7 million women have been victims of these crimes. 23

Ben Tucker, who was killed in a car crash on 4 June at the age of 82, was a jazz bassist who performed with such stars as Quincy Jones to Peggy Lee before he settled in the 1970s in Savannah, where he became one of the Georgia city's best-known musicians.
Tucker, an avid golfer, was driving a golf cart across a road on Hutchinson Island when a car slammed into him at high speed. The driver of the car that struck him was charged with vehicular homicide and other criminal counts.
The news stunned musicians and jazz enthusiasts in Savannah, where Tucker had been a musical fixture for around four decades. Tucker made his living playing upright bass – an instrument he named Bertha and claimed was 240 years old – at jazz festivals, wedding receptions, nightclub gigs and bar mitzvahs.
"One of the most interesting things about playing with Ben was he was so beloved by so many people in Savannah," said Howard Paul, a jazz guitarist who played and recorded with Tucker for more than 20 years. "You could count on being interrupted at least three times in a song because Savannahians would walk up and shake his hand while we were playing."
Before he moved to the Georgia coast, Tucker had success as a songwriter, most notably with "Comin' Home Baby," co-written with the jazz singer Bob Dorough, which was recorded by Mel Torme, Herbie Mann and more recently Michael Bublé. By the end of the 1960s he had toured with Lee and performed and recorded with jazz greats such as Dexter Gordon, Buddy Rich and Jones.
Paul was a young Army lieutenant scheduled to deploy to Operation Desert Storm when he arrived in Savannah 22 years ago. A friend sent him to a nightclub Tucker operated at the time, and the bassist invited him on stage to play that night and all week.
"He was on the music scene for so many years and performed with many of the greatest names in jazz, yet he spent so much time with local musicians and children as well," Paul said. "I think he grew up in an era of jazz musicians where they felt obligated to give back."
Julius "Boo" Hornstein, a Savannah psychotherapist and jazz writer, befriended Tucker and worked with him for years in the Coastal Jazz Association, which organizes the Savannah Jazz Festival. He said Tucker took excellent care of himself for a man in his 80s and kept a steady gig playing Sunday brunch at a Savannah hotel, where he had been scheduled to perform the night of his death.
"He was a working musician right to the end," Hornstein said. "He was so instrumental in the music life of Savannah."

Recent development in wireless communication-based positioning technology brings significant challenge of detecting the weak signal component arriving from the direct propagation path for time-of-arrival (TOA)-based approach. Due to the common obstruction of the direct propagation path in dense multipath environments, identification of the weak direct path in these environments can be very difficult via the classical correlation-based estimator in the presence of interference from significant later arriving multipath components. A new direct path detection scheme using the multipath interference cancelation is presented in this article. For data communication purpose, an iterative estimator with improved accuracy for joint channel and data estimation is first developed; based on which, the interference of multipath components are reconstructed and subtracted from the original received signal. With the aid of the detected data, an enhanced preamble is formulated. The accuracy of direct path detection is substantially improved by using the correlation between the multipath interference-suppressed signal and the enhanced preamble. Semi-analytical expression of the performance of the iterative estimator is derived. The analysis enables the system to determine an automatic stopping criterion to reduce the computational complexity of the iterative process. The performance of the direct path detection is also analyzed in terms of the signal-to-interference-noise ratio (SINR) and compared with that of the conventional approach. Computer simulation results show the superiority of the proposed direct path detection. The accuracy of the positioning system using the proposed method is also evaluated in dense multipath environments.
KeywordsDirect path Later path Multipath interference cancelation Time-of-arrival Dense multipath environment Orthogonal frequency-division multiplexing
Positioning techniques using wireless communication signals have attracted considerable attention, especially in dense multipath environments where the Global Positioning System (GPS) is often unreliable[1, 2]. Potential applications include navigation, location-aware services, and asset tracking[3, 4]. A few positioning system using data communication systems, e.g., cellular network[5, 6], wireless local area network (WLAN)[7], digital television (DTV)[8], ultrawide bandwidth (UWB)[2, 9–11], and wireless sensor networks[12, 13] have been investigated in the literature. In these systems, time-of-arrival (TOA)-based approach is commonly preferred where the timing of the signal arriving from the direct propagation path is estimated and used for further location estimation[14, 15]. However, significant challenges arise in dense multipath environments, where the direct signal propagation path is often blocked by various obstacles such as buildings, pedestrians and slowly-moving vehicles, making the strength of the direct path significantly weaker than those of later paths (LPs) from scattering, reflection or refraction.
TOA estimation can be achieved by the classical correlation-based estimator, where the correlation is performed between a signal templatea and its received version, and the timing of the first detected peak of the correlation output is considered as the TOA[9, 16]. However, this method has limiting factors for positioning system using communication signals. The training sequence, designed for data communications, has limited duration in order to improve the transmission efficiency and therefore, the correlation peak of the first path is not distinct. Furthermore, due to the multipath propagation effect, the desired signal component of the first path is interfered by the superposition of the signal components of the LPs. In this case, the correlation output can exhibit adjacent peaks with similar or larger magnitude due to the large multipath interference, leading to ambiguity in the selection of the correct peak corresponding to the first path. Therefore, it is very difficult to reliably detect the weak direct path from the wireless signals consisting of strong multiple components and thus, large positioning error is inevitable when the direct path is erroneously identified.
To facilitate the TOA estimation with higher accuracy, super-resolution schemes that jointly estimate the amplitude and the relative delay of each path were proposed in[17–19]. Despite the extremely high computational complexity the methods entail, the results show that these estimators do not always lead to good TOA estimation. For real applications with complexity constraints, several simple techniques have been proposed to detect the first path. Energy detection-based method was proposed in[20–23]. However, the energy detector can perform poorly when the strength of the first path is not the strongest one. Meanwhile, threshold-based approach to detect the first path by comparing the correlation output with a particular threshold[20, 24–29] are gaining interests due to their potential for complete analog implementation, and therefore, particularly attractive to low cost battery-powered devices, e.g., mobile receivers. However, the threshold-based correlation estimator with the solutions to the aforementioned practical challenges in dense multipath environments remains large space undisclosed.
We introduced the idea of multipath interference cancelation in[30]; however, with a simple system model and performance evaluation under static channel. Furthermore, the theoretical performance and the practical constraints, e.g., complexity issues, have not been considered. In this article, we propose a direct path detection scheme using multipath interference cancelation for accurate TOA estimation in dense multipath environments. We consider an Orthogonal Frequency-Division Multiplexing (OFDM)-based communication system, which is widely adopted in various broadband wireless applications[31] and demonstrate the feasibility of the proposed direct path detection method in communication-based positioning systems. For data communication purpose, an iterative estimator for joint channel estimation and data detection with progressively improved accuracy is first proposed to achieve better performance of data communication. Based on the output of the iterative estimator, we propose to reconstruct and mitigate the multipath components from the received signals. Data-aided method is also used to construct an enhanced preamble. The new direct path detection is therefore based on the cross-correlation between the multipath interference-suppressed signal and the enhanced preamble. Considering the computational burden for the mobile receivers, the characteristics of the iterative estimator is studied by deriving a semi-analytical expression of the variance of the estimation error and the convergence conditions. An automatic stopping criterion is further developed to avoid the unnecessary computational complexity and allow a tradeoff between the performance degradation and computational burden. The performance of the direct path detection is analyzed by deriving the signal-to-noise-interference ratio (SINR)b. Monte Carlo simulations are carried out to evaluate and verify the performance and effectiveness of different modules as well as the overall method.
The rest of the article is organized as follows. The model of the OFDM-based communication system is presented in Section 'OFDM-based communication system with positioning capability'. The challenges of the classical correlation-based estimator for TOA estimation are also addressed in Section 'OFDM-based communication system with positioning capability'. In Section 'Proposed direct path detection scheme', a new direct path detection scheme using the multipath interference cancelation and data-aided techniques are proposed. Performance analysis is presented in Section 'Performance analysis of the proposed direct path detection method' and demonstrated by Monte Carlo simulations in Section 'Simulation results and discussions'. Finally, we conclude the article in Section 'Conclusion'.

OFDM-based communication system with positioning capability
System model
Classical correlation-based TOA estimator
The conventional approach, which is based on the cross-correlation between the received signal and the local signal template, is widely used in communications as well as positioning systems. The time index of the earliest detected peak on the correlation output can then be converted to the corresponding arrival time of the signal traveling along the direct propagation path. However, our approach aims for positioning with traditional communication systems where the existing signal structures are not originally designed for good positioning capabilities, e.g., short preamble signal, and therefore, the first path can have a weak correlation peak and it is also severely distorted by the interference from later arriving multipath components in dense multipath environments. We now analyze the performance of this method.
- 1.
m-sequence exhibits excellent correlation properties [32] such that the interference components from the LPs in (5) have been minimized by the preamble itself. In this case, the performance gain of the proposed direct path detection over the classical estimator will serve as a lower bound for other cases. Therefore, improved performance gain can further be expected when other types of preambles are used.
- 2.
Unlike some complex-valued sequences, the m-sequence has low hardware implementation complexity which has been widely employed in various research works and real applications, e.g., synchronization in OFDM systems [33, 34].
The SINR can be verified by noting that {h l } are independent, {a n } are known numbers and {w n } are also independent. In wireless environments such as indoor or dense commercial areas, the strength of the direct path is often significantly weaker than the LPs due to the obstructions, e.g.,. Therefore, interference from LPs' components shown in (6) can have large negative impact on the SINR. It is straightforward to see that the duration of the preamble signal p and the interference from the LPs are two main challenges in the detection of the direct path. However, in data communication systems, the preamble signal is used for initial access, synchronization and channel estimation. To optimize the spectral efficiency in cellular networks, the overhead of such training has to be as low as possible to reduce the corresponding redundancy as long as the quality of service requirements are achieved. On the contrary, for positioning systems it is desired to have as long preamble as possible to provide large correlation gain for good timing estimation. To address the aforementioned challenges, we propose a new direct path detection scheme based on multipath interference cancelation and data-aided method in the following sections.
Proposed direct path detection scheme
Iterative estimator for joint channel estimation and data detection
However, the accuracy of LS channel estimation (and hence data detection) is usually not good enough. As our proposed multipath interference cancelation approach relies on the performance of the channel estimator, the improvement given by the proposed approach can be very limited when the LS estimator is used. We therefore propose an iterative estimator to provide accurate channel and data estimation which is of significant importance for further multipath interference cancelation purpose.
The basic idea of the proposed iterative estimator is to utilize data decision feedback to virtually extend the duration of the original preamble signal to refine the initial channel estimation. We want to use both P and the unknown X M in (2) instead of only P to improve the accuracy of channel estimation. An approximation of X M can be first obtained from the tentative demodulated OFDM data based on the initial channel estimation given in (7). However, this approximation is not reliable at the beginning and can be gradually improved when channel estimation improves. Hence, an iterative estimator is needed to progressively provide more accurate channel estimation. Consequently, the accuracy of both data and channel will be enhanced simultaneously as the process is iterated.
The proposed iterative estimator is described as follows:
It should be mentioned that the accuracy of the initial estimation is limited by the length of the preamble. Therefore, the performance of multipath interference cancelation will be dramatically degraded if a short preamble is used.
where we have defined.
Set iteration index i = i + 1. The updated channel estimate is subsequently used for the next round of data demodulation. As the above process is iterated, the channel and data estimation are progressively enhanced. Step 2 is repeated until the automatic stopping criterion is fulfilled. The characteristics of the iterative estimator and the automatic stopping criterion will be derived in the subsequent analysis.
Automatic stopping criterion design
Due to the limited battery life of the mobile devices, an automatic stopping criterion is proposed to terminate the iterative process as early as possible to avoid unnecessary computations while the user-specified requirement is achieved.
- 1.The iterative estimator with data decision feedback should only be used along with the preamble if the resulting variance of channel estimation error is smaller than that obtained during the initial estimation. Based on (9) and (22), it is easy to check that P e max, the maximum P e , that assure the performance improvement when the iterative estimator is used, can be determined by(23)which results in
- 2.It can also be seen from (22) that P e is a function of the variance of the channel estimation error at the symbol detector, and can be given by(24)where the function f can be determined using computer simulations. f(x) is a monotonous increasing function of x within a close interval. Therefore, at the i th iteration, can be given by(25)whereFor the convergence problem, a reasonably good initial channel estimation where only the preamble is used is necessary to guarantee the convergence of the iterative estimator described in (25). Although it is very difficult to derive the analytical results of the iterative process, e.g., estimation error and convergence. We therefore derive a semi-analytical result of the estimation error in (21) and based on which, we can also derive the initial conditions on the channel estimation and SER for the convergence purpose. These conditions are very important and can be used to evaluate the convergence of a given communication system when particular system configuration such as preamble structure, channel estimation algorithm and modulation scheme is pre-defined. In the following, we denote the variance of the channel estimation error of the initialization stage by and it must satisfy the following conditions:
is located in the interval, namely(26)
This condition ensures a reasonably good initialization performance of the iterative estimator.
The variance of the channel estimation error should decrease with an increase in the number of iterations, namely(27)
This condition ensures that the iterative estimator does not diverge.
- 3.Assuming the convergence of the iterative estimator in reasonable conditions, (22) implies that(28)
almost surely, as P e → 0. It should be mentioned that this bias cannot be removed when the length of the preamble and the OFDM data symbol is finite and it serves as a lower bound of the iterative estimator. In fact, P e is dependent on SNR and therefore this bias vanishes as SNR→ ∞.
where ϵ is a user-defined threshold factor depending on the tolerable performance degradation of the receiver. As a small ϵ that results in less performance degradation is often associated with large number of iterations and vice versa. Therefore, we simulate the performance of the iterative estimator with different threshold factors and it will be discussed in Section 'Conclusion'. In real-time application, a tuneable threshold selection device can be equipped such that the user is flexible to adjust the threshold according to its required performance and power condition.
Proposed direct path detection method
Given the channel estimation results from the iterative estimator, the significant paths which introduce dominant interference to the direct path detection can be determined based on the estimated channel. We use a threshold-based method to select the significant paths. Since the practical multipath channels often show some level of sparsity, where very limited channel paths carry significant energy. Usually the total AWGN perturbation from those nonsignificant paths (zero paths) is much higher than the channel energy carried by them. Therefore, choosing a relative high threshold can successfully reject those nonsignificant paths while detecting most of the significant paths.
where and denote the interference-suppressed signal corresponding to the preamble and OFDM data, respectively.
This correlation output can provide significantly higher peak gain due to the use of the virtually extended signal template which consists of the original template and a "dirty template" from data detection results. Furthermore, the impact of the overlay multipath signal components are mitigated.
The earliest correlation peak that exceeds a particular threshold can be considered as the direct propagation path and its timing index is straightforward to be converted to the TOA estimation. Details of the selection of the threshold can be found in[24].
Remark . Note the above method performs well in dense multipath environments, especially in non-line-of-sight conditions[2, 38–41], where the strength of direct path is significantly lower than the LPs. However, in the presence of line-of-sight propagation (strong direct path), the strength of the direct path can be strong w.r.t. the LPs. In this case, the signal component of the direct path may also be mitigated during the multipath interference cancelation stage. We therefore propose the following algorithm to adapt the proposed method to the dynamic wireless propagation environments, ranging from non-line-of-sight condition to line-of-sight condition.

Performance analysis of the proposed direct path detection method
To show the superiority of the proposed approach, we evaluate the SINR of the correlation output in (36) of the proposed method and compare it with (6).
The subsequent analysis are based on the following conditions:
The OFDM time-domain data {x n } and the regenerated data are mutually independent for different n and therefore it is also easy to show that and if m ≠ n;
The channel taps {h l } are independent complex Gaussian random variables with zero mean and variance and mutually independent of the channel estimation errors {Δ h l }. Also,;
For analytical simplicity, we assume that the LPs mitigated by the proposed method carry most of channel energy such that.
Since we have N ≪ p, significant SINR gain can be expected. This conclusion will be further verified through computer simulations in the following section.

aIn data communication systems, the signal template can be a training sequence which is originally designed for multiple access, synchronization or channel estimation purposes.bIn[24], the authors demonstrated the error probability of the direct path detection is a monotonously decreasing function of the SINR. Therefore, to be more intuitive, we characterize the performance of the proposed direct path detection in terms of the SINR.

Product feature
What are the advantages of Propulse Walking Technology?Our range of models equipped with Propulse Walking Technology have: - A bevelled heel with an inverted rear grip system that enables quick contact with the ground, - A grip zone that accompanies your foot motion on the ground following the walking movement, - And finally, a front push-off zone on the big toe to enhance propulsion, which is reinforced to avoid wear- important in this area when practising power walking.
What are the different practices for fitness walking?Power walking is a sport done in regular sessions that can last from 30 minutes to several hours on flat surfaces. It encompasses active walking for well-being, from 5 to 7 km/h, and fast walking for performance, from 7 to 10 km/h. You can use poles for both types of walking in order to give the whole body a workout. This is called Nordic walking. For more information, please visit www.newfeel.com
What are the specific requirements of a walking shoe?In running, there are two main stages: a strong heel strike, the foot leaves the ground with a bound and a push off the front foot. When walking at a fast pace, the contact zone never leaves the ground and it includes the following three stages: the heel strike, the firm grip of the foot with the ground and the push off from the big toe. The shoes equipped with Propulse Walking Technology have been designed to fulfil these special requirements when fitness walking.
What are the benefits of power walking?Power walking is a complete and effective physical activity because it provides a workout for many of the muscles in your body. Like other sports, it offers many advantages for health and staying in shape. It is a widely accessible sport in which you can progress quickly, done for both casual exercise or for performance. Find more information at www.newfeel.com
Field testing of productsAll Newfeel power walking shoes are tested by representative power walkers in conditions identical to those you could experience every day (weather, speed, walk duration, range of ground surfaces). These daily tests allow us to improve our products and provide you with full satisfaction as you use them.
Lab testing of productsLaboratory tests are carried out by Newfeel to validate the properties and benefits of walking shoes such as flexibility (elasticity), abrasion (wear) of the sole and adhesion between the upper and the outsole.

Housed in an isolated bungalow in the village of Meopham, near Gravesend, Kent, the laboratory was capable of producing a ton of amphetamines at a time with a street value of more than pounds 28m. If mixed with other substances it could fetch up to pounds 70m.
Eleven people, including two women, were arrested in raids on addresses in Kent, Surrey, London and the Isle of Man. Two were arrested at the drug factory.
Police seized more than two-and-a-half tons of chemicals that were in the process of being turned into drugs at the bungalow. They also discovered another building five miles away which they believe has been used as a narcotics factory in the past.
Large amounts of Spanish money have been found at another location, leading to speculation that the drug is being sold abroad as well as in Britain.
Amphetamine sulphate - commonly known as speed - which was found at the factory, is popular among youngsters, especially within the dance culture. It increases the user's energy and self-confidence and is becoming increasingly available throughout the country.
The discovery on Friday was the culmination of a 10-month investigation, code-named Operation Sweet, by officers from the South East Regional Crime Squad. Details of the operation were released only yesterday.
Officers found a vat with 20 to 30 gallons of chemicals boiling in a shed at the bungalow. In the loft there were several 50kg drums of chemicals. The factory made pure amphetamine powder.
Detective Superintendent Ray Hussey, from the Regional Crime Squad, said he was extremely concerned at how easy it was to obtain some of the chemicals.

The Transformative CEO
Impact Lessons From Industry Game Changers
By Jeffrey J. Fox, Robert Reiss
The McGraw-Hill Companies, Inc.Copyright © 2012Jeffrey J. Fox and Robert Reiss
All rights reserved.
ExcerptCHAPTER 1
The Transformative CEO
The transformative CEO comes in all sizes, colors, ages, genders, ethnicities. He or she has a different style, personality, background, ability. It is what he or she accomplishes that distinguishes the transformative CEO from all the rest. The transformative CEO turns around companies, creates new industries, revolutionizes the way business is done, commercializes amazing products, changes society. The transformative CEO is obsessed with company culture, customers, innovation, and leadership.
The transformative CEO encourages risk taking, but prevents recklessness. He or she embraces mavericks, free-thinkers, outsiders, as long as they embrace the winning company culture. He or she woos, cajoles, leads her colleagues, but is not interested in winning a popularity contest. The transformative CEO sees opportunities where others see certain failure. The transformative CEO, according to Phil Griffin, president of MSNBC, "must see around the corner." The transformative CEO spots the right wave to ride, and then gets the organization to surf to success. The transformative CEO creates wealth, taxpayers, donations, job security, unlimited futures, grateful communities.
The transformative CEO changes or creates.CHAPTER 2
On Transformative CEOs
Arkadi Kuhlmann (CEO, ING DIRECT): "Never in history have the issues facing the CEO been more daunting and challenging than they are today. We are in a global marketplace. We can be constantly, instantly, visibly in touch with customers, colleagues, suppliers anywhere on the planet. Information, cash, credit, invoices, payments, data, bids, disinformation, rumors flow seamlessly around the world every second of every day. These forces shorten the business cycles. New products must get to markets faster. Competitive responses are faster. Markets occur, evolve, and devolve overnight. Given these immediate pressures, the CEO must align short-term investments and short-term results with long-term, over-the-horizon goals.
"A CEO's term of service keeps getting shorter. Time to build a transformative culture is shorter. Yet, the activities of a company, like multiplying organisms, keep getting more interwoven, more complex, more difficult to measure and manage.
"Our best CEOs will therefore be a rare breed of renaissance individuals: people equally comfortable with art and science, literature and math, Paris, Texas, and Paris, France, society and business. They are individuals who can simplify; who have experience-honed intuition, street smarts; are mentally fast, nimble, and above all, the best CEOs are creative.
"Blending such qualitative and quantitative disciplines is not easy, but it is demanded by the wide range of challenges in the new world. And the blending never stops: the CEO's continuous learning journey is indeed a steep mountain.
"For CEOs, there are countless stakeholders who will vote not once, but daily, relentlessly, remorsefully. They will vote at the cash register, at the annual meeting, in the boardroom, at the banker's office, on LinkedIn and Twitter, and in social media ballot boxes still unimagined. 'Managing in a glass box,' will be literally true.
"Brave and resourceful, creative and effective, will be the hallmarks of the transformative CEO. For the transformative CEO has no choice but to change the game, and to change the game forever."
David Steiner (CEO, Waste Management): "We are transforming from an old- fashioned trash hauler business to an organization that is intent on turning waste into value, thereby, some day, eliminating dumps and landfills. Any time you are going through a transformation, you have to get the big things exactly right. And the biggest thing is to be sure you have the hearts and minds of employees. We want to save the planet. On this matter, our employees are way ahead of the game. I didn't have to win their hearts and minds, I joined them."
Larry Culp (CEO, Danaher Corp.): "Leaders must make sure the organization does not compromise on talent. Leaders must constantly help the company define 'great talent.' Our number one core value is 'The Best Team Wins.' We firmly believe that if you have the right people, aligned on values, skills, competencies, then performance follows. With good people errors in strategy and execution will be limited and quickly corrected when they occur. When an organization has talent throughout, leaders can set the bar high, thoughtfully and fairly, and reset that bar continuously to drive great results."
Pat McGovern (Founder and Chairman, International Data Group [IDG]): "The transformative CEO is constantly in the marketplace meeting with customers and prospective customers. It is in the marketplace where one can spot emerging trends and unfilled customer needs. If you can fill the need with a profitable price, and that price is lower than the economic value delivered to the customer, then you have the rationale to form a business unit. To make the business successful find that person who will love the idea; who will enthusiastically engage customers; and who will hire similarly motivated people who will make it happen. Treat that leader as you would like to be treated: with trust and with frequent, public, visible appreciation."
Robert L. Johnson (Founding CEO, Black Entertainment Television, Founder and Chairman, The RLJ Companies): "The transformative CEO creates something so compelling it changes people's lives and becomes an iconic brand that sustains itself over time. This takes a visionary leader who can inspire talented people to build a company with a culture based on integrity and value creation. Building a company is like parenting a child: need to nurture, plus lots of love, including tough love."
Arunas Chesonis (CEO, PAETEC Corp.): "The transformative CEO must have no fear of failure. Even a bit of trepidation can demoralize colleagues, whose complete confidence in the mission is necessary to succeed. And leaders must have a 'no greed' credo. The team must feel there is a fair sharing of the wealth, the value, they are helping to create. To do otherwise will lose support of key colleagues."
Anne Mulcahy (CEO, Xerox [ret.]): "The main function of the CEO is to create followership. Having a great strategy, having a great execution plan is insufficient to be a good leader. It's about the CEO's ability to deploy, to be credible with your people, to clearly communicate. Followership and building super competent teams are the most important aspects of transformational leadership."
Daniel Lamarre (CEO, Cirque du Soleil): "In Cirque du Soleil's case, the transformation was taking this fabulously creative organization, which performed 7 'traditional' shows (traditional to Cirque) to a globally recognized entertainment business that now has 22 shows on 5 continents. Our lessons are: build on the fundamental values and company culture that keep us unique (which for us is mind-blowing creativity); diversify our performance format and content; preserve our stunning high-level acrobatics, theatricality, and original choreography. All presented with a dollop of the special Cirque du Soleil touch. Of course, this transformation must be executed with the complete knowledge and enthusiastic cooperation of all our people."
Mark Dixon (CEO, Regus): "The transformative CEO is a surfer. Business is a surfing experience. Ride great waves. Set up great businesses. Every ride (I've had eight) is exhilarating, exhausting, better than the one before. You need an alchemy of talented people, skills, ideas, relentless execution, sheer effort. Create a business that is re

The Irony in the Derivatives Discounting Part II: The Crisis
Marc P. A. Henrard
OpenGamma; University College London - Department of Mathematics
December 20, 2009
Libor derivative pricing has changed with the crisis; Libor is not anymore one unambiguous curve as a large basis has appeared between different Libor tenors. A previous approach to derivative discounting is reviewed at the light of those changes. The valuation of so called linear derivatives, the yield curve construction and the valuation of vanilla options is analyzed.

Drought has left 13 million people on the brink of a full-scale humanitarian crisis in West Africa.
Oxfam said tens of thousands of people in the Sahel region could die in the coming months if the international community did not distribute aid immediately.
Western governments and aid agencies risked making the mistakes of last year in the Horn of Africa, where the famine may have been less severe had there been a swifter response, the charity added.
The next harvest in the region is due in October and the United Nations estimates that more than £450m of aid is needed.
