An RIS-enabled Time Reversal Scheme for Multipath Near-Field Channels
Andreas Nicolaides, Constantinos Psomas, Ioannis Krikidis
Time reversal (TR) is a promising technique that exploits multipaths for achieving energy focusing in high-frequency wideband communications. In this letter, we focus on a TR schem…
Optimizing Configuration Selection in Reconfigurable-Antenna MIMO Systems: Physics-Inspired Heuristic Solvers
I. Krikidis, C. Psomas, A. K. Singh +1
Reconfigurable antenna multiple-input multiple-output (MIMO) is a foundational technology for the continuing evolution of cellular systems, including upcoming 6G communication syst…
MIMO with 1-bit Pre/Post-Coding Resolution: A Quantum Annealing Approach
Ioannis Krikidis
In this paper, we study the problem of digital pre/post-coding design in multiple-input multiple-output (MIMO) systems with 1-bit resolution per complex dimension. The optimal solu…
A Novel Temperature-based Model for SWIPT
Elio Faddoul, Yuan Guo, Christodoulos Skouroumounis +1
In this letter, a novel communication paradigm for simultaneous wireless information and power transfer (SWIPT) is proposed, which leverages the thermal characteristics of electrom…
MIMO with Analogue 1-bit Phase Shifters: A Quantum Annealing Perspective
Ioannis Krikidis
In this letter, we study the analogue pre/post-coding vector design for a point-to-point multiple-input multiple-output (MIMO) system with 1-bit phase shifters. Specifically, we fo…
Optimizing Reconfigurable Antenna MIMO Systems with Coherent Ising Machines
Ioannis Krikidis, Abhishek Kumar Singh, Kyle Jamieson
Reconfigurable antenna multiple-input multiple-output (MIMO) is a promising technology for upcoming 6G communication systems. In this paper, we deal with the problem of configurati…
