Abstract :
We report 1 Mb/s data transmission over PWM dimming control signal for a visible light communication (VLC) system based on a simulation. The simulation program is developed using MATLAB and Simulink. In this simulation, the data stream of non-return-to-zero on-off keying (NRZ-OOK) is transmitted together with a dimming signal for brightness control, which has the form of pulse width modulation (PWM). The PWM frame rate is set to 1 kHz to avoid flickering in human eyes. The data rate is set to 20 kb/s and 1 Mb/s. We report eye diagrams of NRZ data streams for 20kb/s and 1Mb/s.
