An Unambiguous Correlation Function With a Sharp Main-Peak for BOC Signal Tracking

This paper proposes an unambiguous binary offset carrier (BOC) correlation function based on a combination of partial correlations composing the BOC autocorrelation, which has a main-peak sharper than those of the conventional unambiguous correlation functions, thus providing a better tracking performance. From numerical results, it is confirmed that the proposed unambiguous correlation function provides a significant tracking performance improvement over the conventional unambiguous correlation functions in terms of the tracking error standard deviation.
