摘要
在无线MIMO(多输入多输出)通信系统中,基于终端的TDOA/AOA混合定位方法能够用于终端自主定位。介绍了一种基于参数信道模型的MIMO信道AOA估计方法,并将估计结果用于混合定位。仿真结果表明此方法有较小的计算复杂度,其性能优于单纯的TDOA定位方法。
In wireless MIMO（Multiple-input multiple-output） communication systems, the hybrid algorithm of TDOA/AOA can be used by MS to locate itself. An AOA estimation scheme based on the MIMO channel of parameters is presented, and the AOA obtained is used in the hybrid algorithm. Simulation results show that the method has less computational complexity and the location performance is significantly improved compared as with the single TDOA location method
