摘要 基于到达时间(timeofarrival,TOA)的简单原理和非视距(nonlineofsight,NLOS)误差的值总是正的附加延时超量的基本理论特性,最后采用几何坐标求值的算法,提出了一种只考虑NLOS误差的到达时间(TOA)定位方法。计算机仿真结果显示,该方法有效的减小了NLOS误差对定位的影响,提高了定位的精度。 In this article , according to some basic theory of Time Of Arrival(TOA) and the basic Non--lAne--of-- Sight (NLOS) property ( the NLOS error is always a negative one). The approach of evaluating geometry coordinates is used. A new location method is developed. From the simulation , it mitigates the NLOS error considerably and the location accuracy is improved.
