Abstract: Disclosed herein is a method of performing visible-light wireless communication using light-emitting diode (LED) illumination, in which Variable Pulse Position Modulation (VPPM) is used for low-speed data transmission and dimming of illumination, and orthogonal frequency division multiplexing (OFDM) modulation is used in a VPPM on period for high-speed data transmission.
