摘要 文章提出了一种新的基于SA(信号衰减)的蜂窝移动定位技术,该技术对实测取得的信号场强分布数据进行统计学分析和特征值提取,建立信号特征—位置数据库,从而对移动终端进行精确定位。该技术基本不受非视距传输效应(NLOS)影响,系统独立性强,结构简单,响应速度快,定位精度可优于20m。 A new mobile location method based on characteristic value abstraction and statistic analysis is create a database including signal character-location phones.NLOS has no effect on this method,which has better then 20 meters. signal attenuation is presented in this paper.In this method, performed on the metrical signal strength data,so that we can data,by which we can get the precise positioning of mobile strong independence and simple structure.The precision can be
