Abstract :
Mobile station position location is one of the important services, which are supported by 3GPP. In this paper, a data fusion model that based on only TDOA measurements and different stage results, which are calculated by the Chan algorithm is proposed. Simulation results in typical wireless radio propagation environments show that positioning accuracy of proposed method is better than the Chan algorithm when the location estimates are corrupted by the nonline-of-sight (NLOS) error and different measurement errors.
