Asynchronous Cell-Free Wireless Networks
Hossein Maleki, Angel Lozano, Hamid Jafarkhani
This paper introduces intentional symbol-level asynchronicity as an interference-management mechanism for the uplink of cell-free networks. Rather than treating timing offsets as i…
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…
Decentralized Parameter-Free Online Learning with Compressed Gossip
Tomas Ortega, Hamid Jafarkhani
We study decentralized online convex optimization when agents communicate over a graph and messages may be compressed. Classical decentralized online methods typically require lear…
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.…
