| 摘 要： | 为解决基于到达时间差(TDOA)定位算法中的定位模糊、测量时差的精确度对定位精度影响较大等问题,通过对TDOA、基于接收信号强度(RSSI)定位算法进行研究分析,提出利用RSSI加权数据融合修正由TDOA算法获得的多个初始位置估计值,从而获得更优位置估计的TDOA/RSSI定位算法.该算法具有计算量小,能有效降低定位误...

| Abstract: | TDOA algorithm for wireless localization is widely used in wireless localization,but the ambiguity problem exists in it and the correctness of time difference has a great influence on localization accuracy.Through the research on TDOA and RSSI algorithms,a new localization algorithm called TDOA/RSSI that utilizing RSSI weighted data fusion to amend several initial position estimates which were gained by TDOA algorithm to obtain a better estimate was proposed.It needs less calculation and achieves lower loca... |
