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…
Frame Error Rate Prediction for Non-Stationary Wireless Vehicular Communication Links
Anja Dakić, Benjamin Rainer, Markus Hofer +1
Wireless vehicular communication will increase the safety of road users. The reliability of vehicular communication links is of high importance as links with low reliability may di…
Towards Cell-Free Massive MIMO: A Measurement-Based Analysis
David Löschenbrand, Markus Hofer, Laura Bernadó +2
Cell-free widely distributed massive multiple-input multiple-output (MIMO) systems utilize radio units spread out over a large geographical area. The radio signal of a user equipme…
A time-variant channel prediction and feedback framework for interference alignment
Zhinan Xu, Markus Hofer, Thomas Zemen
In interference channels, channel state information (CSI) can be exploited to reduce the interference signal dimensions and thus achieve the optimal capacity scaling, i.e. degrees…
On the Degrees of Freedom for Opportunistic Interference Alignment with 1-Bit Feedback: The 3 Cell Case
Zhinan Xu, Mingming Gan, Thomas Zemen
Opportunistic interference alignment (OIA) exploits channel randomness and multiuser diversity by user selection. For OIA the transmitter needs channel state information (CSI), whi…
