Design of 100Mbps white light LED based visible light communication system

In this paper, a high speed visible light communication transceiver module is designed, and a 100Mbps white light LED based visible light communication system is constructed based on this module. Without using a blue filter, we combined the pre-emphasis technology, modulation technology and the back-end equalization technology to improve the bandwidth and data transmission rate of the visible light communication system effectively. The system has advantages of low cost, low complexity, low power consumption and small transceiver module, which can be practical and industrialized.
