摘 要：A criterion of code tracking multipath error envelope based on coherent Early minus late delay lock loop is derived to analyze and simulate the antimultipath performance of Compass navigation signal. The anti-multipath performance of navigation signal is simulated under different multipath-to-direct ratio （MDR）, correlation distance, signal received bandwidth and signal composition. The results show when MDR is a constant, the signal anti-multipath performance will be better on condition of increasing the high frequency component of Compass navigation signal, utilizing narrow correlation distance and wide receiving bandwidth.
