摘　　要：为解决移动台定位时存在的多址干扰和远近效应,提高定位精度,提出了一种基于并行干扰删除的移动台定位算法.该算法利用迭代检测和并行干扰删除来减小不同基站所发下行定位信号之间的由于远近效应造成的严重的多址干扰.仿真结果表明,该算法可以有效地减小定位中下行多址干扰,提高定位精度.A parallel interference cancellation based mobile localization algorithm was proposed to mitigate the multiple access interference and to improve the location accuracy in mobile positioning systems. The proposed algorithm will mitigate the near-far effect and the multiple access interference of positioning signals from different base stations by iterative estimating and parallel interference cancellation. Simulation results show that the proposed algorithm will improve the accuracy of mobile localization.
