PROBLEM TO BE SOLVED: To provide a visible ray communication system that improves the transmission rate relatively to the WDM scheme and removes an influence of inter-color interference to improve communication quality.SOLUTION: A transmission apparatus (100) included in a visible ray communication system (LS2) allocates carrier signal components of an OFDM signal, modulated with transmission information, to a plurality of LEDs of different luminescent colors. Here, the information is added also to a combination of a carrier frequency and an LED wavelength in allocating a carrier signal to an LED while each carrier signal is modulated with the information. |
