Covertness in the Near Field: Maximizing the Covert Region with FDA
Fatemeh Lotfi, Stefan Roth, Anas Chaaban +1
Covert communication in wireless networks ensures that transmissions remain undetectable to adversaries, making it a potential enabler for privacy and security in sensitive applica…
Analysis of One-Bit Quantized Linear Precoding Schemes in Multi-Cell Massive MIMO Downlink
Qurrat-Ul-Ain Nadeem, Anas Chaaban
This work studies a multi-cell one-bit massive multiple-input multiple-output (MIMO) system that employs one-bit analog-to-digital converters (ADCs) and digital-to-analog converter…
Hybrid Digital-Wave Domain Channel Estimator for Stacked Intelligent Metasurface Enabled Multi-User MISO Systems
Qurrat-Ul-Ain Nadeem, Jiancheng An, Anas Chaaban
Stacked intelligent metasurface (SIM) is an emerging programmable metasurface architecture that can implement signal processing directly in the electromagnetic wave domain, thereby…
Unit Cell Phase-Frequency Profile Optimization in RIS-Assisted Wide-Band OFDM Systems
Omran Abbas, Qurrat-Ul-Ain Nadeem, Loïc Markley +1
The reflection characteristics of a reconfigurable intelligent surface (RIS) depend on the phase response of the constituent unit cells, which is necessarily frequency dependent. T…
Enhancing Secret Key Generation in Block Fading Channels using Reconfigurable Intelligent Surfaces
Hibatallah Alwazani, Anas Chaaban
Physical layer security (PLS) is superior to classical cryptography techniques due to its notion of perfect secrecy and independence to an eavesdropper's computational power. One f…
Reconfigurable Intelligent Surfaces Assisted Communication Under Different CSI Assumptions
Bayan Al-Nahhas, Qurrat-UI-Ain Nadeem, Aryan Kaushik +1
This work studies the net sum-rate performance of a distributed reconfigurable intelligent surfaces (RISs)-assisted multi-user multiple-input-single-output (MISO) downlink communic…
