| 摘 要： | 本文基于单次散射双向移动信道模型及信道参数联合估计,利用单基站测得的多条散射路径的到达时延、到达方向和离波方向进行定位,提出了一种非直达波条件下的TDD高精度移动定位算法.随后分析了其定位误差的分布特性.仿真结果验证了非直达波条件下该算法的有效性.

| Abstract: | A NLOS (Non line of sight) high-resolution location algorithm is proposed based on the parameters TOA(Time of Arrival)、DOA(Direction of Arrival) and DOD (Direction Of Departure) of multiple propagation paths,which can be measured simultaneously under the scenarios where single scattering is dominant in the double-array mobile communication system.From the knowledge of DOD,the single scattering path can be reconstructed and so NLOS location problem becomes solvable.Error analysis disclosed the performance of this algorithm.Simulation shows its effectiveness when no line-of-sight propagation paths exist between the mobile station and the base station. |

| Keywords: | non-line-of-sight single scattering direction-of-departure mobile location |
