摘要
目前 ,关于移动台定位的方法有许多种 ,可以根据场强、电波的入射角以及电波在空中传播的时间进行计算。在不同的场合可以使用不同的方法 ,在 TD SCDMA系统中 ,根据其自身的特点 ,利用系统信息广播的内容和随机接入的参数 ,提出了一种计算 MS和基站之间距离的方法。这种方法具有简单、准确、方便的特点 ,可以广泛的在
Currently, there are many kinds of method about how to trace the position of Mobile Station, such as according to electric magnetic field strength, angel of arrive, the time of arrive Different methods are used in different occasions, this paper, according to the characteristics of TDSCDMA system, represents a way to calculate the distance between MS and Base Station with the contents of broadcast system information and random access parameters This is a simple, accurate and convenient method, it maybe widely used in TDSCDMA system
