Generative Large-Array Emulation for DOA Estimation in MIMO Radar via Conditional Diffusion
Adam Umra, Aya Mostafa Ahmed, Aydin Sezgin
Accurate direction-of-arrival (DOA) estimation from a small multiple-input multiple-output (MIMO) radar array is limited by its aperture, while adding antennas increases hardware c…
Self-Supervised Noise2Noise-Enhanced Denoising for Continuous-Scan Air-Plasma THz Spectroscopy
Adam Umra, Oways Alsoloh, Oliver Nagy +2
Terahertz time-domain spectroscopy (THz-TDS) based on air-plasma generation and balanced air-biased coherent detection offers gap-free broadband coverage, but individual continuous…
Design and Practical Validation of a Novel Modulation Scheme for RIS Detection and Identification
Aymen Khaleel, Adam Umra, Aydin Sezgin
The reconfigurable intelligent surfaces detection and identification (RISs-ID) is a critical process that enables a base station (BS) to adaptively assign the appropriate RIS to a…
Measurement-Based Validation of Geometry-Driven RIS Beam Steering in Industrial Environments
Adam Umra, Simon Tewes, Niklas Beckmann +3
Reconfigurable intelligent surfaces (RISs) offer programmable control of radio propagation for future wireless systems. For configuration, geometry-driven analytical approaches are…
