BOC Signal Capature And An Implement On FPGA

Along with development of the global satellite navigation systems including the GPS,Russia's GLONASS,the EU's Galileo system and China's Compass and the regional navigation systems including India's IRNSS and Japan's QZSS,The frequency band for navigation systems become more and more limiter,in order to solve the compatibility problem,Binary Offset Carrier modulation-a new navigation signal has become a key technology and researching focus,this paper focuses on the characteristics and capture for this signal.This paper analyzes the signal structure,the frequency characteristics and the autocorrelation function of BOC,these characteristics are the important basis for capturing and tracking.Based on the analysis of spread spectrum signal acquisition model,this paper analyzes the serial search algorithm,M&H algorithm and F&B algorithm.From the view of multi carrier model.This paper propose an algorithm and implementation,which combining Sidebandfiltting algorithm and PMF-DFT algorithm...
