Abstract:
An apparatus for transmitting data for visible light communication sets up the pulse width control step of pulse width modulation (PWM) in a unit time interval, modulates each symbol of VLC source data input into a PWM signal in accordance with the pulse width control step, generates a visible light modulation signal by controlling the turn-on time or turn-off time of a plurality of light emitting diodes (LEDs) in response to the PWM signal, and transmits the visible light modulation signal.
