摘要/Abstract

摘要： 室内可见光通信技术是基于白光LED（发光二极管）照明光源的无线光通信技术，在机场、医院等严格限制电磁干扰的场合可替代射频通信，应用前景广阔。鉴于室内可见光在传输过程中墙壁反射引起的多径效应对信号传输质量的影响，本文在4.0m×4.0m×2.8m的房间内测量了室内可见光系统光源的光功率分布，结果表明光源的光信号经墙壁反射，会造成严重的多径效应，从而产生码间干扰。本文对室内可见光功率分布的仿真研究进行了实验验证，实验结果与理论仿真研究基本吻合。

Abstract: Indoor visible light communication technology is based on white LED(Light- Emitting Diode) light source of optical wireless communication technology. At the airport, hospitals and other places where there are strict limits of electromagnetic interference, the technology can replace the radio communications, which has profound application prospects. Considering the influence the wall reflections during the indoor visible light transmission has,The indoor visible light illumination distribution was acquired by experimental measurements in a room of 4.0m×4.0m×2.8m. The conclusion shows that the light source of the optical signal reflected by the wall will produce severe multipath effects,and then limits the communication rate. In this thesis, The experimental verification of indoor visible light distribution and simulation research was carried out. Moreover, the results of the experiment nearly agree with the theoretical simulation research.

Key words: Visible light communication, Multipath effects, Illumination distribution
