固态照明正在革新室内照明。目前的白炽灯和荧光灯正被LED快速取代。除了极高的能源效率外，LED还具有其他优点，例如寿命更长，发热量更低，并且在不使用有害化学物质的情况下改善了显色性。LED的另一个好处是它们能够以非常快的速度切换到不同的光强度。这种功能已经产生了一种新的通信技术（称为可见光通信-VLC），其中LED灯具可以用于高速数据传输。本调查提供了一个技术概述和审查现有的文献可见光通信和传感。本文详细介绍了可见光通信系统及其发射机、接收机等各组成部分的特点，可见光通信信道的物理层特性、调制方式和MIMO技术，介质接入技术，系统设计和可编程平台，通信系统的设计和实现方法，通信系统的设计和实现。以及5）可见光感测和应用，例如室内定位、手势识别、屏幕-相机通信和车辆联网。我们还概述了重要的挑战，需要解决，以设计高速移动的网络使用可见光通信。
The solid-state lighting is revolutionizing the indoor illumination. Current incandescent and fluorescent lamps are being replaced by the LEDs at a rapid pace. Apart from extremely high energy efficiency, the LEDs have other advantages such as longer lifespan, lower heat generation, and improved color rendering without using harmful chemicals. One additional benefit of LEDs is that they are capable of switching to different light intensity at a very fast rate. This functionality has given rise to a novel communication technology (known as visible light communication-VLC) where LED luminaires can be used for high speed data transfer. This survey provides a technology overview and review of existing literature of visible light communication and sensing. This paper provides a detailed survey of 1) visible light communication system and characteristics of its various components such as transmitter and receiver; 2) physical layer properties of visible light communication channel, modulation methods, and MIMO techniques; 3) medium access techniques; 4) system design and programmable platforms; and 5) visible light sensing and application such as indoor localization, gesture recognition, screen-camera communication, and vehicular networking. We also outline important challenges that need to be addressed in order to design high-speed mobile networks using visible light communication.
