摘要
非视距(NLOS)误差是蜂窝网定位系统的主要误差源,直接影响基于蜂窝网络的定位系统的推广和应用。针对提高抗NLOS定位精度算法的研究,分别从NLOS传播特性、NLOS鉴别和NLOS抑制算法等几个方面进行了详细的分析和讨论,综述了该领域的最新研究进展,并提出了自己的观点。
Non - line - of- sight error is the key error in cellular mobile position system and directly restricts popularization and application of mobile position system. In this paper, focusing on the main researches on NLOS error mitigation algorithm in cellular location positioning system, such as NLOS error propagation statistics, NLOS identification, NLOS error mitigation algorithm for improving the positioning accuracy are analysed and discussed. The opinions are presented
