RIS-Assisted Radar-Communication Coexistence: Detection Analysis with Channel Uncertainties
Rawan Derbas, Shimaa Naser, Hamad Yahya +3
Reconfigurable intelligent surfaces (RISs) have emerged as a promising technology for improving communication reliability in radar-communication coexistence (RCC) scenarios, partic…
On the Detection Optimality and Exact BER Analysis of NOMA
Tasneem Assaf, Hamad Yahya, Arafat Al-Dweik
Non-orthogonal multiple access (NOMA) detection using successive interference cancellation (SIC) and joint multiuser maximum likelihood (JML) has been extensively studied, although…
T-Parameters Based Modeling for Stacked Intelligent Metasurfaces: Tractable and Physically Consistent Model
Hamad Yahya, Matteo Nerini, Bruno Clerckx +1
This work develops a physically consistent model for stacked intelligent metasurfaces (SIM) using multiport network theory and transfer scattering parameters (T-parameters). Unlike…
Beyond Diagonal RIS: Passive Maximum Ratio Transmission and Interference Nulling Enabler
Hamad Yahya, Hongyu Li, Matteo Nerini +2
Beyond diagonal reconfigurable intelligent surfaces (BD-RIS) generalizes and goes beyond conventional diagonal reconfigurable intelligent surfaces (D-RIS) by interconnecting elemen…
