PURPOSE: A wavelength division multiplexing communication system in a wireless communication system is provided to transceive data without color variation of illumination light according to a space in optical communication using visible light. CONSTITUTION: A wavelength division multiplexing communication system includes an optical transmitter(1000) and an optical receiver(2000). The optical transmitter generates a wavelength range channel by selecting arbitrary wavelength in a broadband light source emitted from a single broadband light source and transmits the channel to a free space using the generated wavelength range channel. The optical receiver selectively receives the modulated signal by each wavelength range channel transmitted from the optical transmitter and restores the original signal from the received signal. |
