• In cellular envirorunents , because of the influence of several adverse factors , such as muitipath , non - line - of sight propagation , noise , interference and channel frequency characteristics , radio statistics measuremenis like tdoa , toa and aoa related to mobile position , the performance of location algorithms mny be significantly degraded and the position estimation of ms is inevitably biased
  在蜂窝网络环境中，由于受多径、非视距传播、噪声、干扰和信道频率特性等多种不利因素的综合影响，使tdoa 、 toa 、 aoa等与移动台位置有关的电波特征测量值不可避免地出现较大误差，从而使各种定位算法的性能显著下降，造成移动台位置估计出现较大偏差。
