Design of an Ethernet- VLC adapter based on FPGA

摘要

A design of Ethernet adapter for visible light communication (VLC) is proposed in this paper. Based on field-programmable gate array (FPGA) technology and Ethernet protocols, the design applies Ethernet to VLC channel, enabling two-way transmission between both channels, giving solution to the conversion of signal between different coding formats. 8B10B DC-balanced encoding/decoding is used for VLC transceivers to ensure reliable and stable communication. At 1000BASE-T duplex mode, the maximum real-time net data rate on the VLC channel is 300Mbps by sending and receiving Ethernet frames in point-to-point communication with optical transceivers using phosphorescent white light emitting diode (WLED).
