摘要

摘要: 针对正交复用二进制偏移载波信号(QMBOC)跟踪时存在的多零点模糊问题,首先比较了模糊消除的常用方法,并对双环跟踪方法进行了理论分析,在此基础上利用二进制偏移载波信号(BOC(1,1))的双环跟踪环路对QMBOC信号进行了跟踪,同时将副载波联合环路纳入双环跟踪方法作研究对比．仿真结果表明,在载噪比高于24 dB·Hz的环境下,BOC(1,1)的双环跟踪误差趋近于0,小于联合跟踪方法下的跟踪误差,实现了良好的处理效果．

Abstract: Aiming at the problem of multi-zero ambiguity elimination in quadrature multiplexed binary offset carrier signal tracking, the common new dual-loop tracking method is theoretically analyzed under the analysis of the common methods of ambiguity elimination, and the dual-loop tracking of the binary offset carrier signal is used to track and simulate QMBOC signal, meanwhile it is compared with the sub-carrier joint loop tracking simulation. The simulation results show that the BOC(1,1) dual-loop tracking error approaches 0 under the environment of the carrier-to-noise ratio higher than 24dB·Hz, which is less than tracking error under the joint tracking method, which is achieving better processing results.
