摘要
为了克服CDMA移动台(MS)定位估计中面临的远近效应问题,该文提出了一种在服务基站(BS)附近布置一种天线阵列,采用TSOA/AOA混合定位技术对MS进行定位估计的方法,分析了采用不同定位法的GDOP分布, 并给出了相应的TSOA/AOA混合定位算法。不同条件下的仿真结果表明,只要AOA测量值达到一定精度,采用这种方法就能对MS进行准确定位。
In order to overcome the near-far problem encountered in CDMA mobile location estimation, in this paper a mobile location method to utilize an antenna array and TSOA/AOA hybrid location technique is proposed, the GDOP distribution of different location methods are analyzed and TSOA/AOA hybrid location algorithm are provided. Simulation results under different condition show that as far as AOA measurements is relatively accurate, mobile can be exactly located by this method.
