摘要

Abstract - Visible light communication (VLC) technology enabling data transmission by modulating solid-state light-emitting diode (LED) devices has attracted much attention recently. However, the transmission rate of VLC remains low due to the low bandwidth performance of LEDs. We present a VLC transmitter consisting of an LED array to enable implementation of a 16-level pulse amplitude modulation scheme, which theoretically increases the transmission rate from 10Mbps to 40Mbps. In addition, the LED array provides sufficient brightness for illumination of office-sized locations. This paper reports an experimental demonstration of a video transmission system based on VLC using a 4x4 LED array.
