基于多径信号的无线定位系统研究

为了获得更好的定位性能,研究了基于多径信号的无线定位系统及其定位方法.首先建立了定位应用系统 模型,并在多径传播环境下,由多个无线基站测得来自移动台的多径信号的电波到达时间和电波信号到达角,通过对多径产生点的处理和加权最小二乘估计,联合多次测量结果来实现移动台的准确定位.然后对影响无线定位性能较大的参数进行计算机实验仿...

Research on location system based on multipath signals

In order to achieve better location performance,wireless location system and its localization method based on multipath signals are researched.Under the multipath propagation environments,the TOA (Time Of Arrival) and Angle Of Arrival of the signals are measured by the BS (base stations),the method combined with the weighted least squares estimation and multiple measurements by using multipath points is proposed to achieve accurate positioning for MS(mobile station).The simulation results show that the prop...
