一种基于TOA的三维推广无线定位算法

鉴于二维坐标下无线定位算法的结果与现实环境有一定的差距，提出了一种在三维空间条件下基于到达时间(TOA)的Chan推广算法。深入比较和分析了影响该算法定位精度的因素，总结了该算法适用的定位条件和定位环境。在不同定位基站数目、待定位移动台的位置和参与定位基站布局等条件下，对该算法进行了大量的模拟仿真，结果表明利用该算法定位结果比较准确，算法有效可行。

A tri-dimensional expansion wireless location algorithm based on time of arrival

In view of the unsatisfactory performance of the wireless location algorithm based on the two-dimensional coordinate, this paper proposes the Chan algorithm on the basis of TOA under the condition of the tri dimensional coordinate. In this paper, the factors that can impact on the accuracy of the position algorithm are analyzed, and the flexibility of this algorithm to different environments and conditions is summarized. A lot of simulation experiments were carried out on the algorithm according to different numbers of locating base stations, the position of the mobile, and layout of the base stations involved in positioning algorithm.
