移动通信网络中的无线定位技术及其应用

Wireless Position Location Technique and Its Applications in Mobile Communication Networks

描述了移动位置业务中采用的主要定位技术并进行综合比较,分析了目前最有发展潜力的达到时间差(TDOA)定位的原理和定位的解析算法,对其定位误差性能进行仿真,仿真结果表明该定位方法能达到较高的定位精度.

Along with the transition of mobile communication from 2G to 3G, the demand of mobile value-added services has been increasing. The LBS （location based service） is one of the most important mobile value-added services. Under such a background, position location techniques play more and more important role. By describing and comparing the main location techniques in the LBS, location method based on TDOA（Time Difference of Arrival）, the most prospective method at present, is analyzed. Some location simulations are carried out and the result of simulation proves that this method can obtain better location precision.
