We present a high-speed visible light communication(VLC) link that uses a commercially available phosphorescent white light-emitting diode(LED). Such devices have few megahertz bandwidth due to the slow response of phosphorescent component,which severely limit the transmission data rate of VLC system. We propose a simple pre-emphasis circuit. With blue-filtering and the pre-emphasis circuit,the bandwidth of VLC system can be enhanced from 3 to 77.6 MHz,which allows non-return-to-zero on-off-keyi...
