RIS-Enabled Smart Wireless Environments: Fundamentals and Distributed Optimization
George C. Alexandropoulos, Kostantinos D. Katsanos, George Stamatelis +1
This chapter overviews the concept of Smart Wireless Environments (SWEs) motivated by the emerging technology of Reconfigurable Intelligent Surfaces (RISs). The operating principle…
Filtering Jump Markov Systems with Partially Known Dynamics: A Model-Based Deep Learning Approach
George Stamatelis, George C. Alexandropoulos
This paper presents the Jump Markov Filtering Network (JMFNet), a novel model-based deep learning framework for real-time state-state estimation in jump Markov systems with unknown…
Joint Active RIS Configuration and User Power Control for Localization: A Neuroevolution-Based Approach
George Stamatelis, Hui Chen, Henk Wymeersch +1
This paper studies user localization aided by a Reconfigurable Intelligent Surface (RIS). A feedback link from the Base Station (BS) to the user is adopted to enable dynamic power…
Multi-Agent Actor-Critic with Harmonic Annealing Pruning for Dynamic Spectrum Access Systems
George Stamatelis, Angelos-Nikolaos Kanatas, George C. Alexandropoulos
Multi-Agent Deep Reinforcement Learning (MADRL) has emerged as a powerful tool for optimizing decentralized decision-making systems in complex settings, such as Dynamic Spectrum Ac…
