The alternative binary offset carrier (AltBOC) signal shares frequency spectrum with the phase shift keying (PSK) signal, enabling us to manage the satellite communication spectrum more efficiently. However, the side-peaks in the AltBOC autocorrelation pose an ambiguity in the AltBOC signal tracking, and consequently, makes the frequency sharing via the AltBOC difficult. Therefore, in this paper, we propose a cancellation scheme of the AltBOC correlation side-peaks. From the numerical results, it is confirmed that the proposed scheme removes the ambiguity in signal tracking caused by the side-peaks completely, and thus, has a much lower tracking error standard deviation (TESD) (i.e., a much better tracking performance) than the conventional scheme.
