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 )一次定位條件下,基于toa的形心定位算法( 2 )一次定位條件下,基于toa / aoa的混合形心定位算法( 3 )連續(xù)定位條件下,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 這種算法具有對nlos誤差不敏感的特性( 4 )連續(xù)定位條件下,基于速度法的抗nlos單小區(qū)定位算法( 5 )定位跟蹤條件下,基于位移差的卡爾曼濾波跟蹤算法本文對每種算法均進行了仿真研究和對比,驗證了它們在減輕nlos誤差上的可行性和有效性。
