Visible Light Communication (VLC) systems are considered as a future green convergence communication technology because of it used for not only illumination devices, but also indoor communication device. In this paper, RGB LED (light emitting diode) characteristics of transmission and receiving are analyzed for VLC systems. The red, green and blue light wave which used for communication in VLC systems have different characteristic of transmission and receiving. For example, the red light wave has good transmission characteristic for transmission power and distance. Also the blue light wave has good transmission characteristic for data rate likewise red light wave. However, the green light wave has low SNR (Signal-to-noise ratio) characteristic compared with red and blue light waves. Therefore, VLC systems take in SNR to make the green LED. In this case, system performance such as data rate, transmission power and bit error rate (BER) are seriously deteriorated to VLC systems. To resolve these problems, in this paper, we used optical filter to separate RGB light waves and then, transmit the main data such as image, video, and etc. using red and blue light waves. Using this method, we obtain the SNR gain for main data transmission and receive, in additional, without increase of system complexity, we transmit additional data. From simulation results, it is confirmed that the proposed scheme is very effective to enhance system performance of VLC.
