Overview of the receiver techniques for BOC modulation signal

The binary offset carrier (BOC) modulation offers improved performance and the opportunity for spectrum sharing while retaining implementation simplicity. However its drawback is the ambiguity of the autocorrelation function (ACF), which induces a complexity in the acquisition process, and a risk of biased measures while tracking. The traditional techniques for the classic BPSK modulated signal have to be revised. This paper summarizes the matching receiver techniques for BOC modulation, in order to avoid missed detection and false tracking.
