摘要
可见光通信系统采用白光发光二极管(LED)作为光源,因而系统具有通信与照明的双重作用,极大地节约了能源。描述了可见光通信的结构与特点,对可见光通信的一些关键技术做了简单的研究,并介绍了可见光通信的发展动态。
The visible light communication （VLC） is a kind of optical wireless communication that uses the white LEDs. In VLC system, white LEDs are used not only as the illuminator in the rooms, but also as the source of the communication system. The configuration, characteristics and key techniques of visible light communication are described. The devolopment status in the field of VLC is introduced.
