摘　　要：移动台无线定位方法通常分为基于移动台的定位、基于网络的定位及GPS辅助定位3种类型,移动台的定位过程则包括2步:第一步,根据定位类型,估计相应的定位参数;第二步,根据估计出的定位参数,采用相应定位算法确定移动台的位置。该文分析了3种无线定位类型的优缺点,重点介绍了基于移动台和蜂窝网络的无线定位方法,包括定位参数估计技术和文献中提出的几种主要定位方法,并分析了各种定位方法的性能。Position location techniques for the mobile station are generally divided into three types,which are the location methods based on the mobile station or the cellular network and the GPS assistance position.The process of the position location consists of two parts.The first part is to estimate the location parameter; and the second part is to determine the MS′s position using the algorithm related to the parameter.The advantages and shortcomings of three main position location techniques are analyzed,with an emphasis on the location methods based on the mobile station and cellular network.The methods of parameter estimation for position location and the main location methods are proposed in the literature are introduced in this paper.The performance of each method is also analyzed.
