| 摘 要： | 通过测量基站3条或更多不同路径的来自移动站的信号到达时间,可以对移动站进行定位。然而信号的非视距传输却极大地影响了TOA定位算法的定位精度,不同的定位算法在不同的条件下获得的定位精度也不同。对几种TOA定位算法(包括最小均方算法、近似最大似然估计算法、残差加权和残差检测算法)在非视距环境下的性能进行仿真,根据仿真结果,在实际应用中可以针对不同的环境选择最合适的定位算法。

| Abstract: | The location of a mobile station(MS)can be got according to three or more arrival time of signals from MS to BS(base station),however,the accuracy of TOA(time of arrival)is influenced by the non-line-of-sight(NLOS)transmission.Different algorithms gain different accuracies in different circumstances.Several TOA algorithms in circumstances of NLOS are simulated,including LS(least square),AML(approximate maximum likelihood),Rwgh(residual weighting)and RT(residual test)algorithm.According to the simulation,the... |
