Abstract

Visible Light Communication (VLC) is emerging as a promising technology to meet thedemands of fifth-generation (5G) networks and the Internet of Things (IoT). This study introducesa novel RGB-LED-based VLC system design that leverages autoencoders, addressing the oftenoverlooked impact of optical-to-electrical (O/E) conversion efficiency. Unlike traditional methods,our autoencoder-based system not only improves communication performance but also mitigates thenegative effects of O/E conversion. Through comprehensive simulations, we show that the proposedautoencoder structure enhances system robustness, achieving superior performance compared totraditional VLC systems. By quantitatively assessing the impact of O/E conversion—a criticalaspect previously overlooked in the literature—our work bridges a crucial gap in VLC research.This contribution not only advances the understanding of VLC systems but also provides a strongfoundation for future enhancements in 5G and IoT connectivity
