Abstract

Multipath is one of main errors in GPS and other spread spectrum systems, it seriously affects the performance of the navigation receiver. In this paper the correlation model under multipath signal is analyzed and we analyze the characteristics of the autocorrelation function starting with it, then a method of detecting jumping-off point of autocorrelation function based on wavelet analysis is proposed, further more, the discriminator result is got to adjust the C/A phase in DLL. Theory analysis and simulation results show that the method is not restricted by the numbers of multipath and sky-wave interference, and better multipath mitigating performance can be acquired than narrow correlation.
