摘要 针对BOC(Binary Offset Carrier)信号的自相关函数存在多峰性,从而造成同步过程中模糊性的问题,提出了一种基于PCF(Pseudo Correlation Function)算法的同步算法。该算法首先将本地伪码和本地副载波调制到本地产生的辅助信号,再将本地调制后的信号与处理后的接收信号进行相关处理,最后将相关结果进行一定形式的运算得到只有一个单峰的相关函数。并且对提出算法进行了性能分析和仿真比较,结果表明该算法能完全消除同步过程中BOC信号自相关函数的模糊性,并且可以通过改变参数的值来提高捕获精度和捕获性能。 For the problem of unambiguity in synchronization which is caused by the autocorrelation function for BOC (Binary Offset Carrier) signals with multiple peaks, a synchronization algorithm based on PCF (Pseudo Cor- relation Function) is proposed. The local auxiliary signal is modulated with local PN code and local subcarrier, and then the result is correlated with received signal. It obtained a correlated function with single peak. Performance analysis and simulation comparison show that the proposed algorithm can be a solution to eliminate unambiguity com- pletely. The acquisition accuracy and acquisition performance can be improved by modifying the Value of parament.
