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…
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.…
Joint Communication and Sensing in RIS-Assisted MIMO System Under Mutual Coupling
Dilki Wijekoon, Amine Mezghani, Ekram Hossain
This paper considers a downlink Reconfigurable Intelligent Surface (RIS)-assisted Joint Communication and Sensing (JCAS) system within a physically-consistent setting, accounting f…
Dual-Function Beam Pattern Design for Multi-Target ISAC Systems: A Decoupled Approach
Wilson de Souza Junior, Taufik Abrao, Amine Mezghani +1
We investigate the beampattern design problem for mono-static multi-user (MU) multi-point-target integrated sensing and communication (ISAC) systems, where a dual-function multiple…
