Analysis of anti-multipath performance based on traditional acquisition algorithm of boc signal
At present, multipath interference is still an inevitable natural influencing factor for high-precision navigation and positioning. The signal transmitted by the satellite is reflected and refracted by the interference of the surrounding environment, which will cause certain error interference to th...

| Summary: | At present, multipath interference is still an inevitable natural influencing factor for high-precision navigation and positioning. The signal transmitted by the satellite is reflected and refracted by the interference of the surrounding environment, which will cause certain error interference to the phase and pseudorange of the direct wave signal. In order to analyze the degree of interference caused by multipath errors in the signal acquisition process, and compare the anti-multipath performance advantages of the acquisition algorithm. In this paper, starting from the formation principle of multipath signals. Based on the analysis of the code loop phase detector technology of incoherent lead minus lag (EML), the MATLAB simulation analysis platform is built, and then The comparison and simulation experiment of multipath error of sine BOC modulation signal and cosine BOC modulation signal is carried out for two traditional acquisition algorithms which are ASPeCT acquisition algorithm and SCPC acquisition algorithm. The simulation results show that the anti-multipath performance of the ASPeCT acquisition algorithm is better than that of the SCPC algorithm. |
