Based on the simulation platform , five kinds of arithmetic which were suitable for different situations was analyzed in this dissertation : ( 1 ) when locating at one time , centoid location method with toa measurements . ( 2 ) when locating at one time , hybrid toa / aoa centoid location method ( 1 )一次定位条件下,基于toa的形心定位算法( 2 )一次定位条件下,基于toa / aoa的混合形心定位算法( 3 )连续定位条件下,速度法抗nlos定位。
( 3 ) when locating continuously , speed location method in nlos environments ( 4 ) when locating continuously , single cell location method based on speed location in nlos environments . ( 5 ) when tracking , kalman tracking for mobile location in nlos situations based on displacement difference . each method was simulated , studied and compared in this dissertation . it was proved that these proposed arithmetic could mitigate nlos propagation errors effectively 这种算法具有对nlos误差不敏感的特性( 4 )连续定位条件下,基于速度法的抗nlos单小区定位算法( 5 )定位跟踪条件下,基于位移差的卡尔曼滤波跟踪算法本文对每种算法均进行了仿真研究和对比,验证了它们在减轻nlos误差上的可行性和有效性。
