基于RSSI和TDOA分层融合的无线定位算法
Mobile vehicle wireless location algorithm based on hierarchical fusion of RSSI and TDOA
摘要
Abstract
In the current Time Difference of Arrival(TDOA)algorithm,there are some problems such as large positioning devia-tion and time reception deviation,which directly affect the positioning accuracy greatly.Among the positioning algorithms,the Re-ceived Signal Strength Indication(RSSI)algorithm has the characteristics of wide coverage and high precision.Therefore,the hierarchi-cal fusion algorithm of TDOA algorithm is proposed after screening and revising with RSSI algorithm.The overall positioning accuracy is further improved.This hierarchical fusion algorithm can improve positioning accuracy and reduce positioning errors caused by chang-es in external environment as much as possible.Through simulation,it can be seen that the feasibility and stability of the layered fusion algorithm are improved compared with the existing fusion algorithm.关键词
