Unambiguous BOC Signal Tracking Based on Partial Correlations

This paper proposes a novel unambiguous correlation function for sine-phased binary offset carrier (BOC) tracking. Modeling a BOC signal pulse as a sum of multiple rectangular pulses, correlating the multiple rectangular pulses with the received BOC signal, and combining the correlations, we construct an unambiguous correlation function with only a single main-peak. The proposed correlation function is confirmed from numerical results to provide an improved tracking performance over the conventional correlation functions.
