Lee, Seong-Ho (Department of Electronics and IT Media Engineering, Seoul National University of Science and Technology)
Light-emitting diodes (LEDs) are modulated using a square wave pulse sequence for flicker prevention and dimming control in visible light communication (VLC). In a VLC transmitter, the high and low bits of the non-return-to-zero (NRZ) data are converted to two square waves of different frequencies, ...
