Abstract: In order to develop a new locating system in CDMA network, this paper proposes a novel TSOA/AOA locating technique, which uses the measurements of Time Sum Of Arrival(TSOA) and Angle Of Arrival(AOA) to locate a move station. It sets up the mathematical model for TSOA/AOA locating, and presents a locating and tracking algorithm based on Extended Kalman Filter(EKF). The feasibility of the algorithm is verified in the simulation.
