摘　　要：通过对检测移动台信号到达2个基站的时间差实现CDMA蜂窝网中移动台定位的方法研究,对该定位技术进行了实际测试,分析了造成蜂窝网络中无线定位误差的原因,提出了实际情况下实现该项技术必须考虑的因素,通过验证,达到了较高的定位精度。A location technique based on reverse link is studied in this paper. In this technique, the mobile station is located by checking the time difference of signal from the mobile station to two base stations in CDMA cellular network. Through testing this location technique in practice, this paper analyzes the reasons of wireless location error and puts forward some considerations of factors when putting this technique into practice. By examination,this technique has a high precision of location.
