A GPS Software Application for Embedding in Software Definable Radios

The Software Defined Radio (SDR) is an enabling technology that is being leveraged across a wide range of areas within the wireless industry to provide efficient and comparatively inexpensive solutions to several constraints posed in current systems. Since SDR-enabled user devices and network equipment can be dynamically programmed in software, this allows them to be adapted to provide richer feature sets and introduce advanced new services that provide more choices to the enduser and new revenue streams for the service provider. In this paper, the principle of operation of a Software GPS Receiver, designed for embedding within a Software Defined Radio, is described and test results are presented showing its operation on an SDR test-bed.
