| Abstract: | By combining LED lighting and visible light communication technology, an indoor visible light communication system is designed based on real-time ethernet video signal transmission. The system uses high-speed MOSFET to directly drive the light source, combines the features of ethernet data, and uses the UDP transport protocol to code the signal with a four-bit to five-bit and No-Return-Zero-Inverse coding method; the receiver recovers the data based on the FPGA dig- ital phase-locked loop technology. The system implements indoor real-time ethernet video visible light communication transmission in a distance of one meter without distortion, thereby, kick-start- ing its practical application. |
