摘要: 该文提出了一种在W-CDMA环境下实现对移动台的定位及跟踪的方法,其中对移动台位置坐标的计算采用基于EOTD的方法,对移动台的跟踪采用马尔科夫链配合相关检测距离门的方法。该方法实用性强,对传统定位方法进行了改进和补充。该文还给出了利用该实现方案和算法在W-CDMA环境下的仿真结果。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.
