  1. In order to reduce the adverse influence of nlos error to location performance, this algorithm firstly makes initial mobile position estimation by mean tdoa / toa measurements, then estimates nlos error within tdoa / toa measurements by parameters of tip 1 channel model, smoothes and reconstructs tdoa / toa measurements, and finally utilizes two step wls computation. the application of this algorithm under different cellular environments is also discussed and its effectiveness is demonstrated by simulation results. finally, the basic location method, location method implementation, network architecture, signaling protocol and interface, and location procedures of wcdma network mobile location are analyzed

    百臼主回大學槽士扭允生攀幢伍第v頁接著,通過對tdo咖a測的分析,本文提出了一種首先利用tdo咖a平均測值對移動臺位置進行初始估計,並利用tipi通道模型參數估計出thoafl 』 oa測值中nlos的大小,然後對tdo … a測值進行平滑與重構,再採用兩次wls計算,以降低nlos對定位性能不利影響的的定位精度提高演算法,討論了這種演算法在蜂窩網路不同環境條件下的具體實施方法,通過詳細模擬驗證了這種演算法的有效性。
