Using Deep Q-learning To Prolong the Lifetime of Correlated Internet of Things Devices
Jernej Hribar, Andrei Marinescu, George A. Ropokis +1
Battery-powered sensors deployed in the Internet of Things (IoT) require energy-efficient solutions to prolong their lifetime. When these sensors observe a physical phenomenon dist…
Joint Sensing and Reception Design of SIMO Hybrid Cognitive Radio Systems
Miltiades C. Filippou, George A. Ropokis, David Gesbert +1
In this paper, the problem of joint design of Spectrum Sensing (SS) and receive beamforming (BF), with reference to a Cognitive Radio (CR) system, is considered. The aim of the pro…
Coordinated Shared Spectrum Precoding with Distributed CSIT
Miltiades C. Filippou, Paul de Kerret, David Gesbert +3
In this paper, the operation of a Licensed Shared Access (LSA) system is investigated, considering downlink communication. The system comprises of a Multiple-Input-Single-Output (M…
Optimal power control in Cognitive MIMO systems with limited feedback
George A. Ropokis, David Gesbert, Kostas Berberidis
In this paper, the problem of optimal power allocation in Cognitive Radio (CR) Multiple Input Multiple Output (MIMO) systems is treated. The focus is on providing limited feedback…
