摘　　要：针对第三方用户对移动台定位的难点,设计了一种单基站定位算法。分形插值算法和三天线场强差分算法用于获取高精度的单基站定位参数,同时介绍了抑制多径效应的选通相关算法。系统的仿真结果表明该定位算法可以提供高精度的定位结果。According to the diffculity of mobile station loction for third party, the location algorithm was designed for single LMU （location measurement unit）. The algorithm of fractal interpolation and signal strength different of three antenna was adopted to advance the location parameter precision. The Strobe correlator algorithm was introduced to mitigate the multipath effect. The simulation result indicates the location algorithm can provide the high accuracy oosition.
