Full duplex Visible Light Communication Platform based on GNU Radio and USRP 2920
An implementation of full duplex Visible Light Communication, based on USRP platform and GNU Radio environment, is proposed in this work. A main downlink communication between a VLC transmitter and a VLC receiver has been implemented, exploiting a set of Pulse Position Modulation (PPM) with different index. A feedback optical channel, integrating two Arduino 1, have been used for the exchange of control messages. Differing from most of experimental works on VLC, this implementation could potentially allows adaptive communication, advanced synchronization techniques and noise mitigation.
