摘要

随着人们对定位服务(LBS)需求的不断增长,室内定位系统越来越受到人们的关注。室内传播环境要求较高,多径和穿障信号传播影响较大,对室内定位有不利影响。NLOS(非视线)传播尤其成问题,应该加以处理。本文提出了一种新型的超宽带定位系统NLOS抑制方法。给出了系统架构,并对所提出的方法进行了描述。并对实验结果进行了讨论。

A new map based method for NLOS mitigation in the UWB indoor localization system
Indoor localization systems are getting more and more attention nowadays, as demand for location based services (LBS) is rising. Indoor propagation environment is quite demanding, with high influence of multipath and through-obstacle signal propagation, such conditions have negative impact on the indoor positioning. NLOS (non-line of sight) propagation is especially problematic and should be dealt with. In the paper a novel method for NLOS mitigation in UWB localization system is presented. System architecture is shown along with the description of the proposed method. Results of the performed experiment are also discussed.
