Abstract

In the recent years, the conventional lighting systems are beginning to be replaced by LED lighting systems. In a Visible Light Communication (VLC) system, the visible light is used to provide a link between a transmitter, who is typically a LED, and a receiver, which is either a photodetector or an image sensor. The VLC can be used, besides illumination, for transferring data by changing very fast the light intensity of the LED and not to be perceived by the human eye as flicker. In recent applications, high frame rate cameras have begun to be used, but their disadvantage is the high cost. This paper proposes and experimentally validates a VLC solution that uses low frame rate camera and does not require a transmitter-receiver synchronization.
