Deep Reinforcement Learning‐Enabled QoS‐Aware Adaptive Modulation for Visible Light‐Infrared Communication Systems

IET Communications, Volume 20, Issue 1, January/December 2026.
To address the challenges of channel sensitivity and reliability in aircraft cabin environments, this paper proposes a reinforcement learning‐assisted bidirectional communication system utilizing visible light for the downlink and infrared for the uplink. By combining an improved, resource‐efficient LMMSE algorithm for channel estimation with RL‐driven

Hardware‐Accurate Simulation and Performance Analysis of Free Space Optical Communication Systems

IET Communications, Volume 20, Issue 1, January/December 2026.
This paper presents a system‐level performance evaluation of a 10 Mbps free‐space optical (FSO) communication link using a novel dual‐testbed methodology. By combining hardware‐accurate profiling in Keil μ$\umu$ Vision for the STM32H755ZI microcontroller with physical layer simulations in Proteus, we successfully isolate embedded processing constraints

Evaluation of Mechanisms for Reliability and Awareness in Platooning Under Low Transmit Power

IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.
Low transmit power, whether due to transmit power control or deliberate settings to reduce interference, improve coexistence or save energy, can undermine the awareness range and beacon reliability needed for safe platooning. This paper evaluates reliability mechanisms and finds that no single mechanism works at very low power without trade‐offs ...
