A real-time high-speed visible light communication (VLC) system based on RGB-LEDs is proposed in this paper. With the use of the wavelength-division multiplexing (WDM), the system enables three individual color channels. The physical layer of the system is based on time-domain synchronous OFDM (TDS-OFDM) technology. Digital pre-distortion method also is applied to improve the SNR performance. Experiment demonstration shows that the proposed system can achieve a peak transmission data rate of 544.32 Mbps in real time with 256-order constellation, transmitting three individual 4K ultrahigh- definition television (UHDTV) signals at the same time. The proposed system is proven to be sufficient for wireless indoor multimedia communication requirements.
