Performance Characterization of gr-owc, the GNU Radio Out-of-Tree Module for Optical Wireless Communications

Volume 3

As researchers continue to investigate novel technologies for next-generations of wireless communications systems, flexible and adaptable tools remain essential for system testing and development. Software-Defined Radios (SDRs) provide flexible and reconfigurable signal-processing capabilities, thereby serving as a crucial platform for the rapid prototyping, testing, and experimental validation of communication systems. GNU Radio is an open-source SDR toolkit that enables the extension of its core software library through the development of..

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..
