Abstract:
Disclosed herein are a visible light communication method and apparatus. The visible light communication method includes determining whether a current location is the start of a symbol of a transmission signal, setting a sample index, a signal accumulated value for an accumulation region of a front half portion of the symbol, and a signal accumulated value for an accumulation region of a rear half portion of the symbol, determining whether the sample index belongs to an accumulation region of the front or rear half portion of the symbol, and accumulating samples of the transmission signal in accordance with the location to which the sample index belongs, determining whether a current location corresponds to the end of the symbol, and outputting a Variable Pulse Position Modulation (VPPM) communication signal corresponding to the transmission signal.
