Multipath detection method based on CCRW-like technique for GNSS receivers

Multipath detection and mitigation has always been paid great attention. In former research, CCRW (Code Correlation Reference Wave) is used for multipath mitigation. A multipath detection method based on CCRW-like technique is proposed in this paper. It’s performance is determined by the wave construct and it can be analised. This method only needs a separate correlation channel to get the detection metirc, which is easier to realize compared to other detection methods And the performance analization method is showed in this paper. This method is analysed based on the hypothesis that there is only one mulitpath, but it applies to scenrios of complex scenrios where there could be many multipath. The detection performance can be analyzed combined with the information of the variance of noise.
