TOA data process method for improving the position location accuracy in NLOS environment

  • 摘要: 基于移动通信环境中非视距NLOS(Non-Line of Sight)传播时延扩展服从指数分布的特性,提出了提高波达时间TOA(Time of Arrival)定位方法精度的一种数据处理方法.该方法首先对TOA测量数据进行分析,从中剔除明显不合理、对定位精度没有贡献、甚至会增加定位误差的测量值,保留误差最小的3个,然后采用最小二乘LS(Least Squares)法对移动台坐标进行估计.仿真数据表明,该数据处理方法不但能够有效提高NLOS传播环境下TOA定位方法的精度,并对视距LOS(Line of Sight)传播条件下的定位精度影响不大,具有较好的环境适应能力.
