The Research on Synchronization Acquisition Technology for BOCsin and BOCcos Phase Modulation Signals

Abstract

BOC (Binary Offset Carrier) modulation technology has been applied to the new generation of satellite navigation systems, because of the unique split-up spectral characteristics and multiple peaks of autocorrelation. On the basis of analyzing the power spectrum and autocorrelation function of the BOC modulation signals, the synchronization acquisition algorithms have been studied for choosing the more efficient un-ambiguity method of the BOC signals. Moreover, taking BOC sine and cosine sub-carrier modulation signals as the examples, the simulation and analysis have been done for the suitable acquisition algorithms.
