An Indoor Real-Time Audio Transceiver System Based on Visible Light Communication

In this paper, a prototype of real-time audio transceiver system using visible light is proposed. The proposed system consists of a transmitter and a receiver, where the transmitter is used to send real-time audio signal by means of commercial LED lamp and the receiver is used to recover the signal from the received optical signal. The experimental results show that the distance for receiving error-free sound signal is up to 10 meter in an indoor environment.
