Abstract:

With the development of the solid state light source, the high power LED has been widely applied in the illumination. The indoor visible light communication system has broad application combining the illumination and the communication. In order to meet the requirement of indoor illumination and communication, a full duplex communication system is structured by designing the transmitter, receiver and interface module based on the intensity modulation and direct detection modulation. The channel model is analyzed. The actual intensity distribution and the reliable communication distance of the one-way link are measured. The experiment proves the feasibility and the reliability of the system.

Key words: optical communication, visible light communication system, illumination, line-of-sight channel, full duplex communication
