component based on the determined phase values, otherwise, discarding the phase values as being unreliable. In accordance with an aspect of the invention, a method for generating reliable channel state information in a wireless multi-user MISO satellite communication system employing precoding is provided. The method comprises the following steps: Preferably, the predetermined threshold value may be /2. Alternatively, the threshold may be selected as a function of the carrier noise levels. Preferably, only for a reference waveform component of the plurality of waveform components, step b) may further comprise : Further preferably, only for said reference waveform component, step c) may further comprise: bl) at the receiver, estimating a frequency value of the reference waveform component, tim e synchronizing said reference waveform component and re-sampling the reference waveform component, to obtain a re-sampled reference waveform component; cl) at the receiver, determining the absolute phase values of said pilot sequences comprised in said plurality of second fields in the frame unit of the re-sampled reference waveform component. d) if the standard deviation of said plurality of phase values is lower than a predetermined threshold value, generating at the receiver a reliable channel coefficient corresponding to the waveform component based on the determined phase values, otherwise, discarding the phase values as being unreliable. c) for said waveform component, determining phase values of the pilot sequences comprised in said plurality of second fields at the receiver; b) for a waveform component of the plurality of waveform components, determining the start of a frame unit of the waveform component, and determining positions of said plurality of second fields at the receiver; a) at a receiver, receiving a signal from a satellite, the signal comprising a plurality of waveform components, each waveform component being subdivided into frame units, wherein each frame unit comprises a first field that is not subjected to precoding and that indicates a start of the respective frame unit and a plurality of second fields that are not subjected to the precoding, each of said second fields comprising a pilot sequence;
