Securing Intelligent Reflecting Surface (IRS)–Aided NOMA Networks in Covert Wireless Communication Using Jammer

International Journal of Communication Systems
ABSTRACTIn this paper, an intelligent reflecting surface (IRS)–assisted non‐orthogonal multiple access (NOMA) network is proposed in a multi‐user scenario where the transmitter communicates with its receiver covertly by helping a friendly jammer. In this network, an adversary detects the communication existence of the users in the frequency band while ...

Design, Development, and Implementation of Intelligent Reflecting Surface (IRS) for Passive Radar Sensing: A Comprehensive Review

International Journal of Emerging Technologies and Innovative Research
This paper presents a concise yet comprehensive review of Intelligent Reflecting Surfaces (IRS) as a novel enabler for passive radar sensing. By dynamically controlling electromagnetic wave reflections, IRSs enhance radar capabilities in non- line-of-sight (NLoS) environments and mitigate limitations such as low signal-to-noise ratio and clutter ...
