Channel-Estimation-Free Beamforming for RIS-Assisted Systems with Limited Feedback
Hossein Maleki, Hamid Jafarkhani
In this article, we consider received-power maximization in RIS-assisted wireless links using only limited received signal strength (RSS) feedback, avoiding explicit estimation of…
An Encoded Corrective Double Deep Q-Networks for Multi-Agent Control Systems
Mohammadreza Barzegaran, Kemeng Han, Hamid Jafarkhani
This paper studies the synthesis of control policies for heterogeneous and interconnected multi-agent systems that collaborate through data exchange over a communication network to…
UAV Energy Consumption Models for Wireless Systems Research: Model Selection and Misconceptions
Mohammadreza Barzegaran, Hamid Jafarkhani
Uncrewed aerial vehicles (UAVs) are gaining increasing attention in wireless systems, providing new opportunities to expand the reach and improve the quality of wireless services.…
Dual-Function Radar-Communication Beamforming with Outage Probability Metric
Hossein Maleki, Carles Diaz-Vilor, Ali Pezeshki +2
The integrated design of communication and sensing may offer a potential solution to address spectrum congestion. In this work, we develop a beamforming method for a dual-function…
Signal Processing and Learning for Next Generation Multiple Access in 6G
Wei Chen, Yuanwei Liu, Hamid Jafarkhani +3
Wireless communication systems to date primarily rely on the orthogonality of resources to facilitate the design and implementation, from user access to data transmission. Emerging…
A Reinforcement Learning Approach for Wildfire Tracking with UAV Swarms
Carles Diaz-Vilor, Angel Lozano, Hamid Jafarkhani
Suitably equipped with cameras and sensors, uncrewed aerial vehicles (UAVs) can be instrumental for wildfire prediction, tracking, and monitoring, provided that uninterrupted conne…
