- Live demonstration: 150Mbps+ DCO-OFDM VLCPublication . Figueiredo, Monica; Ribeiro, Carlos; Alves, Luis Nero; Figueiredo, MónicaThis demonstration showcases the potential of OFDM-based Visible Light Communication (VLC) systems for indoor high-speed communications using off-the-shelf LEDs, suitable for illumination. The physical layer was implemented in a Xilinx Virtex-6 FPGA using System Generator. It was designed with a modular architecture, enabling collaboration with other groups with interest in this field. This demonstration explores the optical front-end out-of-band bandwidth to transmit, showing the usefulness of OFDM-based schemes. Using 64QAM and 25MHz modulation bandwidth, it is possible to transmit over 50cm at 150Mbit/s with a BER smaller than the usual 3.8x10-3 limit.
