摘要

二进制偏置载波(BOC)调制技术以其独特的分频特性和多峰自相关特性被广泛应用于新一代卫星导航系统中。在分析BOC调制信号的功率谱和自相关函数的基础上，研究了BOC信号的同步采集算法，以选择更有效的BOC信号去模糊方法。并以BOC正弦和余弦子载波调制信号为例，对合适的采集算法进行了仿真分析。

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

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.
