RIS Nearfield Position and Velocity Estimation Using a Validated Propagation Model
Thomas Zemen, Musa Furkan Keskin, Moustafa Rahal +5
We investigate reconfigurable intelligent surfaces (RISs) for the task of position and velocity estimation in non-LOS (NLOS) indoor scenarios, using a snapshot based multi-step est…
Adaptive RIS Control for Mobile mmWave NLoS Communication Using Single-Bit Feedback
Hamed Radpour, Markus Hofer, Thomas Zemen
Reconfigurable intelligent surfaces (RISs) are emerging as key enablers of reliable industrial automation in the millimeter-wave (mmWave) band, particularly in environments with fr…
Ray Tracing Algorithm for Reconfigurable Intelligent Surfaces
Sara Sandh, Hamed Radpour, Benjamin Rainer +2
Ray tracing accelerated with graphics processing units (GPUs) is an accurate and efficient simulation technique of wireless communication channels. In this paper, we extend a GPU-a…
Reconfigurable Intelligent Surface for Industrial Automation: mmWave Propagation Measurement, Simulation, and Control Algorithm Requirements
Hamed Radpour, Markus Hofer, David Loschenbrand +4
Reconfigurable intelligent surfaces (RISs) enable reliable low-latency millimeter wave (mmWave) communication links in cases of a blocked line-of-sight (LoS) between the base stati…
