Performance Improvement of VLC Systems Employing an Amplify-and-Forward Scheme

Abstract

Visible light communications (VLC) are a novel technology that employs LEDs lamps to transfer data between devices, and has the potential to improve wireless communications in the following years. Relay-based cooperative communication, a technique developed for RF communication, takes advantages of spatial diversity without the need of additional resources on the communication transceivers. In this paper, we present a simulation model for the VLC channel with amplify-and-forward cooperative cooperation and show that it can improve the performance of such systems at indoor scenarios.
