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…
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…
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…
Information Theoretic Analysis of a Dual-Band MIMO Cellphone Antenna with ANSYS HFSS SBR+
Volodymyr Shyianov, Bamelak Tadele, Vladimir I. Okhmatovski +1
Historically, the design of antenna arrays has evolved separately from Shannon theory. Shannon theory adopts a probabilistic approach in the design of communication systems, while…
Unlabeled Compressed Sensing from Multiple Measurement Vectors
Mohamed Akrout, Amine Mezghani, Faouzi Bellili
This paper introduces an algorithmic solution to a broader class of unlabeled sensing problems with multiple measurement vectors (MMV). The goal is to recover an unknown structured…
Lens-Type Redirective Intelligent Surfaces for Multi-User MIMO Communication
Bamelak Tadele, Faouzi Bellili, Amine Mezghani +2
This paper explores the idea of using redirective reconfigurable intelligent surfaces (RedRIS) to overcome many of the challenges associated with the conventional reflective RIS. W…
Next-slot OFDM-CSI Prediction: Multi-head Self-attention or State Space Model?
Mohamed Akrout, Faouzi Bellili, Amine Mezghani +1
The ongoing fifth-generation (5G) standardization is exploring the use of deep learning (DL) methods to enhance the new radio (NR) interface. Both in academia and industry, researc…
