摘要

随着可见光通信技术的发展和基于位置服务的需求，基于可见光通信的室内定位系统(VLC)已成为一个热门的研究领域。但多路径对定位精度有重要影响(定位误差为1m)。本文用归一化信噪比(SINR)来表征多径信号。然后提出了一种能够计算信噪比并消除多径影响的LOS-NLOS识别算法。仿真结果表明，定位精度可分别达到7 cm和20 cm。

LOS-NLOS identification algorithm for indoor visible light positioning system

With the development of Visible light communication (VLC) and the requirement of position based service, VLC based Indoor Positioning System (VLC IPS) has been a popular research area. But there is an important impact of multipath on positioning accuracy (1m positioning error). In this paper, the multipath is characterized as normalization Signal to Interference plus Noise Ratio (SINR). Then the LOS-NLOS identification algorithm is proposed which can calculate the SINR and eliminate the effect of multipath. According to simulation result, the positioning accuracy could achieve a 7 cm and 20 cm in the corner area.
