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
在蜂窩網路環境中，由於受多徑、非視距傳播、噪聲、干擾和通道頻率特性等多種不利因素的綜合影響，使tdoa 、 toa 、 aoa等與移動臺位置有關的電波特徵測量值不可避免地出現較大誤差，從而使各種定位演算法的性能顯著下降，造成移動臺位置估計出現較大偏差。
