Abstract:	The tracking of BOC (Binary Offset Carrier) signals is possible using the algorithms designed for the BPSK (Binary Phase Shift Keying) signals tracking since both have a carrier spread by a code sequence. Nevertheless the spreading sequence of BOC signals has a pattern that splits and shifts the spectrum allowing the sharing of the frequency band with other signals. This results in cross-correlation function of BOC signals having many peaks surrounding the main one. If the BPSK signals tracking algorithms are adopted for BOC signals without any change there is no guarantee for these algorithms to lock on the main peak. This paper suggests a tracking technique capable of detecting and correcting for BOC correlation function side peak tracking. The new technique has been implemented on a software receiver. Promising results were obtained in modeled severe multipath environments.
