CV Quantum Communications with Angular Rejection Filtering: Modeling and Security Analysis
Mohammad Taghi Dabiri, Meysam Ghanbari, Rula Ammuri +3
Continuous-variable quantum key distribution (CVQKD) over free-space optical links is a promising approach for secure communication, but its performance is limited by turbulence, p…
AI Assisted Next Gen Outdoor Optical Networks: Camera Sensing for Monitoring and User Localization
Meysam Ghanbari, Mohammad Taghi Dabiri, Rula Ammuri +2
We consider outdoor optical access points (OAPs), which, enabled by recent advances in metasurface technology, have attracted growing interest. While OAPs promise high data rates a…
Deep Learning Surrogate for Fast CIR Prediction in Reactive Molecular Diffusion Advection Channels
Meysam Ghanbari, Mohammad Taghi Dabiri, Mazen Hasna +2
Accurate channel impulse response (CIR) modeling in molecular communication (MC) often requires solving coupled reactive diffusion-advection equations, which is computationally exp…
Hierarchical Deep Learning for Joint Turbulence and PE Estimation in Multi-Aperture FSO Systems
Mohammad Taghi Dabiri, Meysam Ghanbari, Rula Ammuri +2
Accurate characterization of free-space optical (FSO) channels requires joint estimation of transmitter pointing errors, receiver angle-of-arrival (AoA) fluctuations, and turbulenc…
