Abstract
A visible light communication (VLC) transmitting apparatus modulates source data to an orthogonal frequency division multiplexing (OFDM) symbol according to an OFDM modulation method, inserts a diffusion code that is allocated to the VLC transmitting apparatus into a frequency axis of the OFDM symbol, converts the OFDM symbol in which the diffusion code is inserted to a visible light modulation signal, and transmits the converted visible light modulation signal. Thereby, a signal of the VLC transmitting apparatus in which a VLC receiving apparatus wants can be easily detected.
