Improvement the Algorithm of UWB Wireless Location Based on TOA/TDOA

This paper discusses the theory of UWB(ultra wide band) wireless locating on a basic of research UWB.We first introduce the theory of UWB ranging and locating and do some simulation to verify the accuracy of UWB wireless location in multi-path environment.And then,we bring in the relativity of nodes to enhance the location performance considering there are always many nodes in an Ad Hoc network.The result of simulation shows that the algorithm can enhance the location performance in an Ad Hoc network which ...
