| 摘 要： | 提出了一种不需要任何非视距传播测量值先验信息且具有解析表达式解、非递归的双曲线定位算法。通过一步简单残差加权得出一个与真实移动台位置比较接近的初始定位估计,利用该初始值构造了一个加权矩阵,进行两次加权最小二乘计算,得出了一个最后的定位结果。理论分析与目前流行定位算法的仿真结果比较表明,该定位算法能有效地抑制非视距传播误差的影响,计算量相当小。

| Abstract: | A new non-line-of-sight location algorithm based on TDOA for mobile station is developed in this paper. One of the advantages of this method is that no statistical models or prior information on NLOS channel condition are needed. Simulation and comparison of performance with other existing methods have shown the effectiveness of NLOS error mitigation in location estimate. Its good characteristics including low requirement, non-iteration, very low computational complexity make it easily available to apply to practice. |

| Keywords: | non-line of sight propagation time difference of arrival wireless location WLS estimation |
