一种实用无线定位算法

在移动通信系统中,利用CELLID定位的方法是最简单最快速的,但是该方法只能利用手机接收到的基站信息来确定基站位置,从而推测移动台的位置,因此误差较大,与实际路径不符。本文提供一种利用本地均值来改进该定位精确性的方法,消除毛刺。仿真结果表明,该方法显著改善了CELLID方法的误差,消除了不规则跳跃的点,使路径与真实路径更吻合。

A practical wireless location algorithm

In mobile communication systems, CELLID is the simplest and most rapid positioning method.However, this method can only determine the location of the base station by base station information of mobile photo, to speculate the location of the mobile station.The error is so large that the path is not match with the actual path.This paper provides a way to improve the positioning accuracy and remove the burrs by using the local mean.The simulation results show that,this method significantly reduces the error of CELLID method,eliminate the irregular jumping point,to make the path in accordance with the real path.
