A multipath mitigation technique for finite bandwidth Sine-phased BOC signals is presented. The proposed method is based on two-dimension (2-D) tracking structure, and designed based on the features of 2-D cross-correlation function derived in this paper. This method can provide considerable multipath performance improvement comparing with the traditional dual estimate tracking (DET), and performs better when the BOC modulate order increases, which can be used in high precision applications where the multipath is the major error.
