【摘要】 基于蜂窝的定位与基于卫星的定位都是当今无线定位的研究热点。采用基站TDOA定位和采用同步卫星TDOA定位技术进行比较 ,给出了各自的TDOA定位的算法 ,并分别对TDOA定位性能进行了仿真和分析 ,表明两种定位方法基本原理相同 ,各有优缺点 ,在应用中通常将两者相结合以适应不同环境的定位需要。更多还原

【Abstract】 The location technology based on cells and satellites is widely paid attention today. In this paper, a comparison for TDOA location technology of the base station with that of synchronous satellite is firstly given. Then, the algorithms for two location technology are presented, respectively, and their performances are evaluated and analyzed. The conclusions show that the basic location principle of the two TDOA location methods is the same and each has its advantages and shortages. They should be combined to meet the different situations in application.更多还原
