SDRA2021 - 02 - Antonio Constanzo: Full duplex visible Light Communication Platform based on GNU-R.
Antonio Costanzo is a member of INRIA Lille Nord Europe (France), as postdoc at Future Ubiquitous Network (FUN) team. His main interests are optical systems, antennas, applied electromagnetism, RF design and remote sensing. His present activities mainly deal with prototyping, development and test of Visible Light Communication Systems for IoT applications.
In this work, we implement a full duplex Visible Light Communication (VLC) based on USRP platform and GNU radio environment. The system is composed of a main downlink channel between a VLC transmitter and a VLC receiver, for which we have implemented a Pulse Position Modulation technique with different index. A feedback channel between the VLC receiver and the VLC transmitter is also developed, based on two Arduino 1. This feedback channel is used for sending control messages from the receiver, that can be used for the implementation of adaptive techniques, such as the dynamic change of the modulation based on the receiver state.
