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…
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,…
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…
Frequency-packed Faster-than-Nyquist Signaling via Symbol-level Precoding for Multi-user MISO Redundant Transmissions
Wallace A. Martins, Symeon Chatzinotas, Björn Ottersten
This work addresses the issue of interference generated by co-channel users in downlink multi-antenna multicarrier systems with frequency-packed faster-than-Nyquist (FTN) signaling…
