Abstract

With the use of smart antenna in the third generation of mobile communications location,it is possible to measure the angle of the arrival of signals.By introduction of loose variables in location parameters and using iterative calculation on the basis of TDOA/AOA location algorithm,most of the influence of NLOS propagation can be eliminated,and the location accuracy is increased.This method is good for the futural cellular network location.
