A Novel Cosine-Phased Binary Offset Carrier Signal Tracking

This paper addresses a novel cosine-phased binary offset carrier (BOC) signal tracking, enabling an unambiguous signal tracking. Two novel locally-generated signals are first obtained by dividing the cosine-phased BOC sub-carrier into multiple parts, and then, cross-correlations between each of the locally-generated signals and the received signal are generated. Finally, the cross-correlations are efficiently combined, yielding a correlation function with no side-peaks, thus consequently, removing ambiguity in signal tracking. The tracking error performance comparison between the proposed and conventional correlation functions shows us that the proposed correlation function can offer a significant improvement in performance compared with the conventional correlation functions.
