Abstract :
In this paper, a tracking algorithm with NLOS (non-line of sight) errors for MS (mobile station) in cellular networks is proposed. Initial evaluation of MS location is obtained by TDOA location method based on BP neural network. A Kalman filter is used to modify the initial evaluation of MS location and track the location with detection thresholds. Simulation result shows that the tracking algorithm can perform dynamic tracking to MS effectually.
