【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]:In order to solve the problem of general ambiguity free acquisition analysis of binary Offset Carrier Bocs and its derived signals, this paper aims to solve the problem that there is a lack of fuzzy capture for binary offset carrier carrier and its derived signals at present. In this paper, a fuzzy free acquisition algorithm is proposed for all BOC signals and all modulation orders. Firstly, a general subcarrier model is constructed according to the relationship between the subcarrier waveforms of different modulated signals. The general expression of the signal is obtained, and then the secondary wave is decomposed according to the half-period, and then the general acquisition method is constructed according to the synthesis method of the correlation function. The theoretical and simulation experiments show that. The new acquisition method is suitable for all kinds of BOC signals with all modulation orders. It can eliminate the secondary peak completely and realize the fuzzy-free acquisition. The acquisition accuracy and the anti-multipath performance are greatly improved compared with other algorithms.
