摘要

提供移动用户准确的定位业务是未来无线通信发展的必然趋势.但是由于非视线(NLOS)传播的存在

无线定位始终是一个难点.本文先介绍视线(LOS)传播时的定位方法

然后提出NLOS消除算法和虚拟基站移动NLOS消除方法.通过仿真和比较

说明两种方法获得较好的效果.

Abstract

Two novel location algorithms with Non-Line-of-Sight(NLOS)propagation considered are introduced.By inserting some loose varables to represent NLOS

an iterative method was introduced to mitigate the influences of NLOS propagation.The other one is

by moving the base stations virtually

to increase the distances between the base stations and the mobile to replace NLOS with Line-of-sight(LOS)

then use the maximum-likelihood estimation and iterate until the solution converges.The simulations and comparisons show these two methods are more effective.
