摘　　要：通过对BOC信号机理的研究,提出用平方倍频检测法来检测BOC调制信号的载波频率,利用其相关性对解调出的BOC基带信号的副载波频率以及伪随机码速率进行检测,并通过MatLab模拟仿真BOC(1,1)信号来测试算法的有效性,结果表明该算法能有效地实现对BOC信号的载波频率、副载波频率和扩频码速率的检测。Through the mechanism of the BOC signal, proposes a method named Square Multiplier Detection to detect carrier frequency of BOC modulated signal. Detests the subcarrier frequency and the pseudo-random code rate of BOC baseband signal by the correlation of BOC. With the BOC （1, 1） signal, the Matlab simulation tests the validity of the algorithm which can effectively achieve the detection results of BOC signal carrier frequency, subcarrier frequency and spread spectrum code rate.
