Research on Distance Measurement Performance of Beidou B1C Signal

摘要

Aiming at the complexity of the new system B1C signal system and the characteristics of many components, the ranging performance research on B1C signal is carried out. The theoretical analysis is carried out from two aspects: code tracking accuracy and multipath error analysis, and BOC(1,1) non-matching is adopted. The received RMS bandwidth and associated output signal-to-noise ratio and code tracking errors at different intervals are analyzed and compared. The simulation results show that the theoretical code tracking accuracy of B1C signal pilot component is the lowest, and the multipath performance is better than BOC(1,1) signal. In the study of non-matching method, better output can be obtained with wide interval. The error indicates that the performance of non-matching reception under certain conditions is better than the matching algorithm.
