针对BOC(Binary Offset Carrier)调制信号的功率谱密度的频谱分裂的特点和自相关函数的多峰性的特性,在通过仿真分析BOC(10,5)调制信号自相关函数和功率谱密度的特点的情况下,提出了一种用于BOC(10,5)的信号单边带BPSK-like捕获算法,有效解决了BOC调制信号捕获过程中易发生副峰错捕和多副峰干扰的问题,降低了捕获的模糊度。通过对该算法进行Matlab仿真,验证了该算法具有较好的捕获性能且易实现。

According to the BOC(Binary Offset Carrier)characteristics of the power spectral density of the modulated signal spectrum splitting and autocorrelation function of multiple peaks,through the simulation analysis of BOC(10,5)signal autocorrelation function and power spectral density of the characteristics of the situation,put forward a BOC(10,5)signal sideband BPSK-like acquisition algorithm,effectively solves the problem of BOC(Binary Offset Carrier)are prone to side peaks of wrong arrest and multiple pair peak interference problems process to capture the modulation signal,reduces the capture of ambiguity.The algorithm is simulated by Matlab,and it is proved that the algorithm has better capture performance and is easy to implement.
