- 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
