Towards Joint Optimization for UAV-Integrated RIS-Assisted Fluid Antenna Systems
Ali Reda, Tamer Mekkawy, Theodoros A. Tsiftsis +2
Unmanned aerial vehicles (UAVs) integrated into cellular networks face significant challenges from air-to-ground interference. To address this, we propose a downlink UAV communicat…
Demonstration of an Integrated Terahertz Band-Stop Filter Using an Apodized Bragg Grating
Ali Dehghanian, Walid Gomaa, Mohsen Haghighat +2
This paper presents the demonstration of an on-chip integrated Terahertz (THz) Apodized Bragg grating (TABG) which functions as band-stop filter with a center frequency of 0.8 THz…
Accelerating genetic optimization of nonlinear model predictive control by learning optimal search space size
Eslam Mostafa, Hussein A. Aly, Ahmed Elliethy
Genetic algorithm (GA) is typically used to solve nonlinear model predictive control's optimization problem. However, the size of the search space in which the GA searches for the…
Information-Theoretic Limits for Steganography in Multimedia
Hassan Y. El-Arsh, Amr Abdelaziz, Ahmed Elliethy +1
Steganography is the art and science of hiding data within innocent-looking objects (cover objects). Multimedia objects such as images and videos are an attractive type of cover ob…
Flexible Architecture for Real-time Processing of Multiple Video Signals
Mohamed Awad, Islam T. Abougindia, Ahmed Elliethy +1
Simultaneous processing of multiple video sources requires each pixel in a frame from a video source to be processed synchronously with the pixels at the same spatial positions in…
Achieving Positive Covert Capacity over MIMO AWGN Channels
Ahmed Bendary, Amr Abdelaziz, C. Emre Koksal
We consider covert communication, i.e., hiding the presence of communication from an adversary for multiple-input multiple-output (MIMO) additive white Gaussian noise (AWGN) channe…
