Study on Weakening Influence of GDOP for WLAN Wireless Location Accuracy

Weakening influence of GDOP for location accuracy is the key problem for realizing high accuracy WLAN wireless location.The related problems are studied thoroughly,and mathematics theory of GDOP are firstly deduced and analyzed,then it is proposed that adopting residual weighting algorithm can obviously weaken influence of GDOP for WLAN wireless location accuracy,finally by simulating,it proves its rationality and usefulness,and it can obviously enhance location accuracy of MS.This has important meaning for realizing high accuracy WLAN wireless location.
