Abstract：In this paper, we proposed a low speed audio communication system using visible light which is suitable used in indoor communication.In the system, the unidirectional total data rate is 22.37kbit/s used OFDM Adaptive bit loading with BER under pre-FEC limit of 3.8 ×10 -3 after 1.2m free-space transmission, which have a white LED as a transmitter and the audio interface of smart mobile using a High-sensitivity Photodetectors ( PIN) as a receiver.The 3.5mm headphone channel is a standard interface for all intelligent terminals with high compatibility, and VLC is a way of indoor broadband access, which has been received more and more attention.With this development, the 3.5mm headphone channel based on VLC will be popular.
