提出了一种二进制偏置载波（BOC）调制信号的快速无模糊捕获技术。我们删除的模糊性（侧峰）的BOC自相关函数（ACF），利用一个降低复杂性（真实的和对称）的过滤器组成的只有七个非零样本。所提出的方案适用于通用正弦和余弦相位BOC信号。理论和仿真结果表明，该方法消除了捕获问题中的模糊性，而不需要在接收机中的辅助信号。
This paper proposes a fast unambiguous acquisition technique for binary-offset-carrier (BOC)-modulated signals. We remove the ambiguities (side peaks) of the BOC autocorrelation function (ACF), exploiting a reduced-complexity (real and symmetric) filter composed of only seven nonzero samples. The proposed scheme is applicable to both generic sine- and cosine-phased BOC signals. Theoretical and simulation results show that the proposed method removes the ambiguities in the acquisition problem without requiring an auxiliary signal in the receiver.
