The Channel Pre-processing Module And Hardware Implementation For Anti-jamming Satellite Navigation Receiver

In recent years, satellite navigation anti interference in space domain is an important technique,some new problems are brought now, for the amplitude and phase error will influence theperformance of the digital beamforming. In this dissertation, signal processing modules in thechannel amplitude/phase error correction algorithm and capture algorithms are given in detail fromthe engineering point of view. This work can be divided into two main parts:1. multi-channel between the satellite navigation signal amplitude and phase error correction,the first part is the serious impact of channel signal processing, which also leads to the necessity ofcorrection, and through theoretical analysis and MATLAB simulation shows the two low-complexityreceiver-channel amplitude/phase error correction algorithm, and finally describes a receive andtransmit channel amplitude and phase error correction algorithm based on hardware platform, theabove algorithms in several engineering applications have low computational complexity and highefficiency.2. capture of satellite navigation signals, which is based on the GPS navigation system and thesignal structure, focusing on the serial search arithmetic and parallel search arithmetic, then on thehardware platform of a serial code phase acquisition algorithm for parallel frequency studied byMATLAB simulation and hardware debug verify the feasibility of the method.
