Cancellation of Correlation Side-Peaks for Unambiguous BOC Signal Tracking

Based on a combination of the sub-correlation functions composing the autocorrelation of the binary offset carrier (BOC), we propose a novel cancellation scheme of correlation side-peaks to solve the ambiguity problem in the BOC signal tracking. The proposed scheme is applicable to both generic sine- and cosine-phased BOC signals without requiring any auxiliary signal in the receiver. Avoiding the ambiguity problem, the proposed scheme is confirmed from numerical results to provide a better tracking accuracy than the conventional schemes.
