| Abstract: | The Taylor series expansion algorithm is improved in this paper by using located results of the residuals weighted algorithm as the initial values of the Taylor method,and utilizing the minimum residuals instead of the mean square error in the TDOA which is not easy to obtain in practice.The simulation results show that this algorithm can effectively suppress the influence of NLOS error in location estimate,and has good stable characteristics. |
