A Time-Difference-of-Arrival Location Method Based on Residual Sorting and Weighted Matrix amended
In the cellular network, the NLOS(Non-Line-of-Sight) propagation of signals is the key factor of affecting positioning accuracy. Based on the COST259 model, this paper is aimed at selecting the best measurements from all of the measuring combinations by residual sorting and changing the weight coefficient with modifying the covariance matrix in Chan algorithm, the integration of the above two measures can mitigate the NLOS errors effectively. The simulation results show that the amended algorithm can improve the location accuracy and efficiency in the condition of NLOS propagation to some extent and meet the demands of E-911.
