Intelligent Reflecting Surface-Aided Visible Light Communications: Potentials and Challenges

Abstract

To satisfy the explosive growing traffic demands in wireless communications, visible light communication (VLC) performs as a promising technology due to its broad and license-free bandwidth. However, practical VLC systems usually confront challenges, such as blockage and high path loss. Different from traditional VLC techniques, intelligent reflecting surface (IRS)-aided VLC can achieve a remarkable performance gain.
