Combining Relaying and Reflective Surfaces: Power Consumption and Energy Efficiency Analysis
Zaid Abdullah, George C. Alexandropoulos, Steven Kisseleff +2
Hybrid relaying networks (HRNs) combining both a relay and an intelligent reflective surface (IRS) can lead to enhanced rate performance compared to non-hybrid relaying schemes, wh…
Coverage Probability of STAR-RIS assisted Massive MIMO systems with Correlation and Phase Errors
Anastasios Papazafeiropoulos, Zaid Abdullah, Pandelis Kourtessis +2
In this paper, we investigate a simultaneous transmitting and reflecting reconfigurable intelligent surface (STAR-RIS) assisting a massive multiple-input multiple-output (mMIMO) sy…
On the Impacts of Phase Shifting Design and Eavesdropping Uncertainty on Secrecy Metrics of RIS-aided Systems
Long Kong, Steven Kisseleff, Symeon Chatzinotas +2
This paper investigates the secrecy outage probability (SOP), the lower bound of SOP, and the probability of non-zero secrecy capacity (PNZ) of reconfigurable intelligent surface (…
Successive Decode-and-Forward Relaying with Reconfigurable Intelligent Surfaces
Zaid Abdullah, Steven Kisseleff, Konstantinos Ntontin +3
The key advantage of successive relaying (SR) networks is their ability to mimic the full-duplex (FD) operation with half-duplex (HD) relays. However, the main challenge that comes…
Simultaneous Control Information and Power Transmission for Reconfigurable Intelligent Surfaces
Steven Kisseleff, Konstantinos Ntontin, Wallace A. Martins +2
Reconfigurable intelligent surfaces (RISs) are planar structures with attached electronic circuitry that enable a partially programmable communication environment. RIS operation ca…
Toward Autonomous Reconfigurable Intelligent Surfaces Through Wireless Energy Harvesting
Konstantinos Ntontin, Alexandros-Apostolos A. Boulogeorgos, Emil Björnson +9
In this work, we examine the potential of autonomous operation of a reconfigurable intelligent surface (RIS) using wireless energy harvesting from information signals. To this end,…
