【摘要】 随着移动通信的发展,利用无线蜂窝通信定位的需求日益迫切。尤其是美国联邦通信委员会(FCC)E-911条例中有关定位要求,对利用无线蜂窝通信定位技术的研究起了很大的推动作用。提出了一种基于TDOA的实际可行的定位实现方案和算法。该算法实用性强,对传统定位方法进行了改进和补充。该实现方案的另一优点是不需要各基站同步。给出了利用该实现方案和算法在W-CDMA环境下的仿真结果和性能分析。更多还原

【Abstract】 The location services in cellular systems have become more and more important with the development of wireless communication in recent years. This paper researches the wireless location based on the time difference of arrival (TDOA) in the wide code division multiple access (W-CDMA) system. At the same time, this paper presents a scheme and algorithm. The algorithm is very robust and can enhance the performance of the traditional algorithms. At last, this paper gives the results of the simulation and performance analysis.更多还原
