Mitigating SAR-ADC Non-Idealities in Massive MU-MIMO Systems via Affine Models
Jérémy Guichemerre, Christoph Studer
Low-resolution data converters can significantly reduce the power consumption and silicon area of all-digital massive multi-user (MU) multiple-input multiple-output (MIMO) basestat…
Efficient and Physically-Consistent Modeling of Reconfigurable Electromagnetic Structures
Alexander Stutz-Tirri, Georg Schwan, Christoph Studer
Reconfigurable electromagnetic structures (REMSs), such as reconfigurable reflectarrays (RRAs) or reconfigurable intelligent surfaces (RISs), hold significant potential to improve…
Neural Integrated Sensing and Communication for the MIMO-OFDM Downlink
Ziyi Wang, Frederik Zumegen, Christoph Studer
The ongoing convergence of spectrum and hardware requirements for wireless sensing and communication applications has fueled the integrated sensing and communication (ISAC) paradig…
A Software-Defined and Distributed Wi-Fi Channel-State Information Acquisition Testbed
Frederik Zumegen, Christoph Studer
We propose a software-defined testbed for Wi-Fi channel-state information (CSI) acquisition. This testbed features distributed software-defined radios (SDRs) and a custom IEEE 802.…
