Joint Linear Precoding and DFT Beamforming Design for Massive MIMO Satellite Communication
Vu Nguyen Ha, Zaid Abdullah, Geoffrey Eappen +9
This paper jointly designs linear precoding (LP) and codebook-based beamforming implemented in a satellite with massive multiple-input multiple-output (mMIMO) antenna technology. T…
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…
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…
Double-RIS Communication with DF Relaying for Coverage Extension: Is One Relay Enough?
Zaid Abdullah, Steven Kisseleff, Konstantinos Ntontin +3
In this work, we investigate the decode-and-forward (DF) relay-aided double reconfigurable intelligent surface (RIS)-assisted networks, where the signal is subject to reflections f…
