Abstract
The visible light communication apparatus includes: a brightness signal generator that calculates a duty cycle of an driving signal corresponding to brightness requirement information and generates clock frequency information on brightness signals based on the calculated duty cycle; a transmission data generator that generates transmission data; an illumination driver that generates and outputs an driving signal in a pulse waveform based on the clock frequency information of the brightness signals and the transmission data and controls a pulse position of a turn on section for each bit unit time in the waveform of the driving signal based on the transmission data; and an illumination that is operated according to the driving signal from the illumination driver.
