Abstract:
In a visible light communication system, a transmission device includes a data modulation section which assigns 1-bit information to each of visible lights of RGB, and modulates transmission data into 3-bit modulation data. An LED light emission section transmits a multiplexed visible light signal, in which the RGB visible lights are multiplexed in accordance with the modulation data.
