This 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.
