Summary:Visible light communication is a new type of communication technology that combines both lighting and communication functions. In this paper, the principle of communication channel model under the condition of one-way light source is analyzed, and a reverse transmission scheme of visible light is designed. The experimental results show that the system can realize downlink communication link communication under the condition of single light source under visible light and DQPSK based modulation mode, and the downlink communication link has no interference and the communication effect is good.
