New Correlation Functions for CBOC Satellite Signal Synchronization

Binary Offset Carrier (BOC) signal synchronization is based on the correlation between the received and locally generated BOC signals. Thus, the multiple side-peaks in BOC autocorrelation are one of the main error sources in synchronizing BOC signals. Recently, a new correlation function with no side-peaks was proposed for sine or cosine phased BOC signal synchronization by the authors. In this paper, they propose a novel correlation function for Composite Binary Offset Carrier (CBOC) signals by using the similar method to that, which has a better power ratio than the CBOC autocorrelation.
