基于WCDMA上行链路的多信标辅助定位

The wireless location base on W-CDMA forward link by the beacons

本文提出了在蜂窝小区中加入辅助定位信标实现W-CDMA环境下的移动定位,并提出了一种实用性强的定位实现算法。该方案另一优点是实现代价小,一改传统需要多个基站参与定位的做法,从而避免了WCDMA中相邻小区之间的同信道干扰。本文还给出了利用该实现方案和算法在W-CDMA环境下的仿真结果和性能分析。

This paper gives a new method about the cell wireless location through adding some beacons in the cell in the wide code division multiple access (W-CDMA). At the same time, this paper give a robust and efficient algorithmic. It change the method that need more than three bases participate in location, and avoid the cochannel interference. In addition, the performance of the proposed wireless cellular location and tracking method is evaluated through simulations.
