一种基于移动台位置的动态定位算法

根据检测电波到达时间（TOA）的定位法提出了一种基于移动台位置的动态定位算法。该算法利用蜂窝网络系统中多个基站检测到的移动台电波TOA信息对移动台进行定位估计，参与定位估计的基站数目及其定位算法中相应的权值随移动台与服务基站的距离自动动态改变。计算机模拟结果表明，该算法在3种典型移动通信信道环境中都能得到较好的定位效果。

A Mobile-Location Based Dynamic positioning Algorithm

In this paper,a mobile location-based dynamic positioning algorithm is proposed based on measured time of arrival(TOA). This algorithm can be used in cellular networks to estimate mobile location from mobile radio TOA information detected by several base stations(BS). The BS numbers and the corresponding weights utilized in this algorithm can be dynamically adjusted according to the distance between mobile station(MS) and serving BS. Location estimate can also be made if only TOA and angle of arrival(AOA) are measured by serving BS. Therefore, this algorithm could be applied to many mobile communication channel environments. Simulation results show that the location performance of this algorithm is satisfactory in three typical mobile communication channels.
