An OFDM testbed for LiFi performance characterization of photovoltaic modules

Abstract

OFDM-based wireless communications are widely used for digital data RF transmissions. This very efficient modulation scheme should prove to be one of the solutions for future VLC (visible light communications) systems. More-over, for outdoor applications, photovoltaic modules seem to be interesting alternatives to photodiode-based classical detectors. They are indeed known to offer a higher level of resilience to saturation effects. In this article, we present LiFi performance results obtained from an OFDM-based LiFi testbed using various photovoltaic modules as photodetectors.
