Abstract :
In the indoor, wireless location system based on time difference of arrival(TDOA) has poor anti-interference ability, in the system, especially the non-line-of-sight is the largest interference which causes position´s results serious distortion. An algorithm for identification of non-line-of-sight is presented to improve the anti-interference ability of the location system, the non-line-of-sight is identified and discarded by two measurements´ comparison and measurements analysis between each base station and mobile station, it enhances the anti-interference ability and stability of the system.
