移动场景下一种可见光通信系统的设计与实现
Design and implementation of a visible light communication system based on the mobile scenario
摘要
Abstract
Compared to traditional wireless communication technologies, visible light communication, an emerging wireless communication technology with the dual functions non-electro of lighting and communication has attracted great attention for the advantages of not occupying radio frequency spectrum, non-electromagnetic interference or radiation.Based on the research of existing visible light communication technology, the modulation and encoding theories of visible light communication were further discussed in this paper.A layout mode of LED light source and a special driving circuit were proposed and designed to realize a wide coverage of light.Finally, a visible light communication system was implemented based on mobile scenario.In the case, when the transmission end is 3 m away from the receiver, the signal can be sensitively received in moving state (only with 200 ns delay), and the visible light communication rate can reach 0.5 Mbit/s, while the effective visible light coverage can attain the range of 5 m×5 m.关键词
