Abstract

The Non Line-of-Sight (NLoS) issue is considered as a key challenge to mature indoor localization technologies. Using Time of Arrival (TOA) on Ultra-wideband (UWB) signal is able to provide fine localization accuracy if NLoS-biased anchor nodes can be identified. In this paper, an antenna cluster selection scheme is proposed to identify the NLoS-biased node, therefore improve the localization accuracy and provide location-aware communication service. In particular, the area of interest with NLoS human body blockage is divided into multiple convex hull based effective localization areas (ELAs). Four antennas, from a distributed antenna system, are deployed in each ELA, where the most severely NLoS-biased antenna is identified and discarded, two other antennas are selected to execute a 2-dimension (2D) indoor localization. The remaining antenna uses this location information to provide location-aware communication service. Performance is evaluated using a channel sounder's measurement data and a simulator, benchmarked to the traditional parametric identification method.

定位-通信双模式下天线簇的选择

非视距(NLoS)问题被认为是对成熟的室内定位技术的一个关键挑战。在超宽带(UWB)信号上使用到达时间(TOA)可以提供较好的定位精度，前提是可以识别出nlos偏差锚节点。本文提出了一种天线簇选择方案来识别nlos偏置节点，从而提高定位精度，提供位置感知通信服务。特别地，NLoS人体阻塞感兴趣的区域被划分为多个基于凸包的有效定位区域(ELAs)。在每个ELA中部署了来自分布式天线系统的四个天线，其中最严重的nlos偏置天线被识别并丢弃，另外两个天线被选择用于执行二维(2D)室内定位。剩余的天线使用这个位置信息来提供位置感知通信服务。利用通道测深仪的测量数据和模拟器对性能进行评估，并对传统的参数识别方法进行基准测试。
