Abstract: In view of problem of short transmission distance and high cost of existing point to point digital communications system, multi-channel digital audio communication system based on visible light transmission was designed and implemented by use of white LED. The system combines audio codec chip of TP3067 to implement multiplexing transmission of multi-channel audio signals, and uses FPGA as the main controller to control time slot of encoder signals. Experimental results show that the system can achieve transfer rate of up to 2.048 Mbit/s, and audio signal of up to 32-channels can be transmitted stably.
