Abstract :
Binary offset carrier (BOC) signal synchronization is one of the most important steps to recover the navigation data in global navigation satellite system (GNSS) including Galileo and global positioning system (GPS). The main error sources in synchronizing BOC signals are the multiple side-peaks in the BOC autocorrelation and the multipath delay. Recently, a novel correlator receiver for the BOC signal was proposed by Garin (shaping correlator receiver), which was shown to shrink the side-peaks and mitigate the multipath effect to a certain degree. However, a shaping correlator receiver cannot completely remove the side-peaks and is affected by a wider multipath delay range than that of the traditional correlator receiver. Moreover, it is applicable to only BOC(n, n) signal. In this paper, we propose a new correlator receiver for BOC signals. The proposed correlator receiver does not have any side-peak in its correlator output, and has smaller multipath delay range that incurs the tracking error than that in the shaping correlator receiver. Furthermore, the proposed correlator receiver is applicable to various types of BOC signals (i.e., BOC(kn, n)) and requires only a half of the number of the correlators used in the shaping correlator receiver.
