摘要

摘要: 针对目前对二进制偏移载波(Binary Offset Carrier, BOC)及其衍生信号的通用无模糊捕获分析匮乏的问题，该文提出一种适用于所有BOC类型信号及所有调制阶数的无模糊捕获算法。该算法首先根据不同调制信号副载波形之间的联系构建出了通用副载波模型，得到信号的通用表达式，然后在此基础上将副载波形按半周期进行分解，再根据相关函数的合成方法构建出通用的捕获方法。理论与仿真实验表明，新提出的捕获方法适用于所有类型及所有调制阶数的BOC信号，能够完全消除副峰，实现无模糊捕获，捕获精度以及抗多径性能相比其他算法都有很大提高。

Abstract: For the unambiguous general acquisition for Binary Offset Carrier (BOC) and its derivative signals is still scarce of analysis, a new unambiguous algorithm is proposed for all types of BOC signals and all kinds of modulation order. Firstly, the common sub-carrier model is constructed according to the links of different sub-carrier modulation. Then according to the common sub-carrier model the general expression of the signals is got. On this base, the sub-carrier is broken down into many half periods. Last, a general capture method based on a combined correlation function is proposed. Simulation results indicate that the proposed method can deal with all kinds of BOC modulated signals including complex ones with different phases or orders. An unambiguous correlated function can be obtained by the proposed method. The main peak width of correlated function is narrowed and the accuracy of capture is improved.
