Sum Rate Optimisation for IRS-Assisted VLC Systems with Time Delay Considerations Using Deep Q-Learning
Volume 3
Visible light communication (VLC) is a promising solution for high-speed indoor wireless connectivity, offering advantages such as license-free spectrum and enhanced physical-layer security. However, VLC performance is highly dependent on line-of-sight (LoS) conditions and is vulnerable to signal degradation caused by device orientation and dynamic obstructions. To address these challenges, this paper proposes a deep Q-Learning (DQL) framework for resource optimisation in intelligent reflecting surfaces (IRS)-assisted VLC systems. A realistic..
