Design and achievement of the visible light Audio communication system

We propose a design of visible light communication which is based on the white LED power source. The design possesses effective software flowchart and the optimized circuit of the hardware modules which include power supply, signal amplification, LED driver, Audio signal transmission, Audio signal reception, filter and amplifier and Audio output. The testing of the design shows our system can realize the short-distance transmission of MP3 audio signal. Due to the advantages of stable performance, little distortion, low cast, simplicity and feasibility, our design owns a strong practical significance in the promotion of visible light communication technology.
