摘要 针对复合二进制偏移载波(multiplexed binary offset carrier)调制信号自相关函数的多峰对接收机的捕获和跟踪造成模糊性的问题,讨论了MBOC调制信号时域波形、功率谱及自相关函数的特性。采用自相关副峰消除技术(ASPeCT,auto-correlation side-peak cancellation technique)对MBOC调制信号的数据通道和导频通道进行了捕获算法研究和仿真分析,并与传统方案的捕获结果进行了比较。MATLAB仿真结果表明,利用ASPeCT方法能有效消除BOC调制信号的捕获模糊性。 Aiming at the ambiguity in acquisition and tracking of the MBOC signal, which is caused by the multi-peaks of the auto-correlation function, the paper discusses the characteristics of the time waveform, power spectrum density and auto-correlation function of the MBOC signal. An acquisition algorithm for both the data component and pilot component of the MBOC signal, which is based on the ASPeCT(auto-correlation side-peak cancellation technique), is analyzed and simulated. This actuation algorithm has been compared to the traditional one. The results of MATLAB simulation shows that the acquisition algorithm based on the ASPeCT can cancel the ambiguity in actuation of BOC signal.
