Abstract: This paper proposes a new method for the wireless cellular locating and tracking. The method is based on the E-OTD to get the position of the MS, and the MS profile is tracked on the bases of Markov models and detection gate. This method is concise and robust. In addition, the performance of the proposed wireless cellular locating and tracking method is evaluated by the simulations. -
