摘　　要：We propose a configuration of a wavelength division multiplexing （WDM）-visible light communication （VLC） system using orthogonal frequency division multiplexing （OFDM） modulation and an adaptive Nyquist windowing of the OFDM signal in the receiver. Based on this configuration, we demonstrate a 750-Mb/s WDM-VLC transmission based on RGB light-emitting diode （LED） with a distance of 70 cm. The measured bit error rate （BER） for all channels are under the pre-forwaxd error correction limit of 3,8 × 10-3. The BER performances of all the channels of the proposed WDM-VLC system show considerable improvement compared with those of the system without Nvauist windowing.We propose a configuration of a wavelength division multiplexing （WDM）-visible light communication （VLC） system using orthogonal frequency division multiplexing （OFDM） modulation and an adaptive Nyquist windowing of the OFDM signal in the receiver.
