Abstract:
In this paper, a novel two-stage unambiguous tracking scheme for binary offset carrier (BOC) signals is proposed. In the first stage, we generate an unambiguous correlation function with a low and narrow main-peak by combining partial correlations of BOC autocorrelation. In the second stage, by combining the unambiguous correlation function with partial correlations, we construct an unambiguous correlation function with a higher and sharper main-peak. From numerical results, we confirm that the proposed unambiguous correlation function offers a better tracking performance than the conventional unambiguous correlation functions in terms of the tracking error standard deviation.
