Power Minimization under Quality of Service Constraints for MIMO Systems with a RIS-based Transmitter
Erico S. P. Lopes, Lukas T. N. Landau, Amine Mezghani
This study investigates a virtual multiuser multiple-input multiple-output (MU-MIMO) system with PSK modulation, realized with a reconfigurable intelligent surface (RIS)-based tran…
Deep Unfolding for SIM-Assisted Multiband MU-MISO Downlink Systems
Muhammad Ibrahim, Amine Mezghani, Ekram Hossain
To improve the efficiency of scarce radio-frequency (RF) resources in next-generation wireless systems, an intelligent transceiver architecture based on stacked intelligent metasur…
Information Rates of Approximate Message Passing for Bandlimited Direct-Detection Channels
Daniel Plabst, Mohamed Akrout, Tobias Prinz +2
The capacity of bandlimited direct-detection channels is challenging to compute or approach due to the receiver non-linearity. A generalized vector approximate message passing (GVA…
Are Stacked Intelligent Metasurfaces (SIMs) Better than Single-layer Reconfigurable Intelligent Surfaces (RISs) for Wideband Multi-user MIMO Communication Systems?
Muhammad Ibrahim, Amine Mezghani, Ekram Hossain
Cascaded or stacked intelligent metasurfaces (SIMs) have emerged as a promising technology to overcome the physical limitations of single-layer reconfigurable intelligent surfaces…
Guided Wireless Technology for Near-Field Communication
Mohamed Akrout, Amine Mezghani, Faouzi Bellili +1
Guided wireless technology is an innovative approach that combines the strengths of guided waves and wireless communication. In traditional wireless systems, signals propagate thro…
Multi-Objective Optimization for Joint Communication and Sensing in Multi-user MIMO Systems: Characterizing the Pareto Boundary
Thakshila Perera, Amine Mezghani, Ekram Hossain
This paper investigates the Pareto boundary performance of a joint communication and sensing (JCAS) system that addresses both sensing and communication functions at the same time.…
