Research on Visible Light Communication Technology

Visible light communication system uses white light emitting diode (LED) as light source, so the system has the dual role of communication and lighting and has high transmit power without taking radio spectrum, electromagnetic interference and electromagnetic radiation, what's more, it could save energy efficiently and so on. This paper describes the characteristics of visible light communication technology, introduces the visible light communication framework and discusses some methods which can improve the performance and quality of visible light communication. Finally, the future application of visible light communication is prospected.
