Description
Summary:Time Division Multiple Access (TDMA) is a practical multiple access technology in modern communication systems. In TDMA communication system, terminals share wireless channel resources in the form of frame-time slots. A frame is divided into multiple time slots, and the duration of each time slot is fixed. In order to locate TDMA communication terminal by a single station, this paper presents a method of joint direction and time finding information based on the assistance of TDMA terminal with known location. In this method, the problem is constructed as a least squares model, and then the target location is obtained by using grid search strategy. Then, the positioning error is analyzed theoretically, and the influence of direction finding error, time measuring error, observation station position error and reference terminal position error on positioning error is studied. Finally, the positioning performance of the proposed method is verified by several simulation experiments.
