Abstract

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.
