Design and Simulation of VLC Transmitting System

Pinqi Zheng, Qingsheng Yu

Abstract


Low ripple and large bandwidth VLC (Visible Light Communication) transmitting system driven by switching current source is designed to use common LED as transmitter for VLC. Active ripple compensation circuit is designed to eliminate inductance current ripple of switching current source. Wallman differential circuit is adopted to realize LED brightness modulation for transferring information. Simulation results show that the design of VLC transmitting system meets the needs of VLC.
