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…
From Prompt to Prototype: Towards a Frontier LLM Driven RF Engineering Workflow
Markus Heinrichs, Oscar Moschner, Simon Tewes +3
Agentic coding environments give a frontier large language model (LLM) direct access to a workstation's terminal, file system, and software. This work demonstrates they extend to p…
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
