Design Of GPS Software Receiver Based On DSP

This dissertation researches a realization method of Global Position System(GPS) receiver based on software radio theory. The emphasis of this research is that overall the receiver is realized in digital signal processor (DSP) by pure software method that can efficiently save hardware resource and cost and carry out easier and more flexibly.In the main body of this dissertation,we expatiate on the characteristic of GPS signal,the structure and work principle of digital correlator and introduce how to search ,capture and track the GPS signal in detail.At last,we give the software flow chat of each module about the GPS software receiver based on DSP.This dissertation expatiates a realization method of GPS software receiver.Software receiver has various uses in military application as well as commerce,and has good developing expectation.
