Reconfigurable Intelligent Surface Aided Amplitude- and Phase-Modulated Downlink Transmission
Qingchao Li, Mohammed El-Hajjar, Ibrahim Hemadeh +3
New reconfigurable intelligent surface (RIS) based amplitude and phase modulation schemes are proposed as an evolution how the phase-only modulation schemes available in the litera…
Performance Analysis of Active RIS-aided Systems in the Face of Imperfect CSI and Phase Shift Noise
Qingchao Li, Mohammed El-Hajjar, Ibrahim Hemadeh +3
The linear minimal mean square error (LMMSE) estimator for active reconfigurable intelligent surface (RIS)-aided wireless systems is formulated. Furthermore, based on the moment-ma…
Statistical CSI-based Beamforming for RIS-Aided Multiuser MISO Systems using Deep Reinforcement Learning
Mahdi Eskandari, Huiling Zhu, Arman Shojaeifard +1
The paper presents a joint beamforming algorithm using statistical channel state information (S-CSI) for reconfigurable intelligent surfaces (RIS) for multiuser MISO wireless commu…
Self-Interference in Full-Duplex Multi-User MIMO Channels
Arman Shojaeifard, Kai-Kit Wong, Marco Di Renzo +3
We consider a multi-user multiple-input multiple-output (MIMO) setup where full-duplex (FD) multi-antenna nodes apply linear beamformers to simultaneously transmit and receive mult…
Massive MIMO-Enabled Full-Duplex Cellular Networks
Arman Shojaeifard, Kai-Kit Wong, Marco Di Renzo +3
In this paper, we provide a theoretical framework for the study of massive multiple-input multiple-output (MIMO)-enabled full-duplex (FD) cellular networks in which the self-interf…
Joint Antenna Selection and Spatial Switching for Energy Efficient MIMO SWIPT System
Jie Tang, Daniel K. C. So, Arman Shojaeifard +2
In this paper, we investigate joint antenna selection and spatial switching (SS) for quality-of-service (QoS)-constrained energy efficiency (EE) optimization in a multiple-input mu…
