Abstract:
Disclosed herein are a visible light communication method and apparatus. The visible light communication method includes determining a dimming level variable to perform minute dimming control, selecting an upper dimming symbol and a lower dimming symbol, which belong to Variable Pulse Position Modulation (VPPM) symbols, based on the dimming level variable, determining at least one of the number of upper dimming symbols to be sent and the number of lower dimming symbols to be sent based on the dimming level variable, and generating a transmission sequence corresponding to the dimming level variable by combining the upper dimming symbols and the lower dimming symbols based on the number of symbols to be sent.
