| Abstract: | Weakening influence of GDOP for location accuracy is key problem for realizing high accuracy WLAN wireless location. We studied thoroughly about related problems; and we first deduced and analyzed mathematics theory of GDOP, then we proposed that adopting residual weighting algorithm can obviously weaken influence of GDOP for WLAN wireless location accuracy, finally by simulation we proved its rationality and usefulness, and it can obviously enhance location accuracy of MS. This has important meaning for realizing high accuracy WLAN wireless location. |
