Generalized Framework for a Fair Comparison of Cellular and Cooperative Massive MIMO Systems
Leonard Paul Schulz, Stefan Schwarz, Gerhard Bauch
Cooperative massive multiple-input multiple-output (MIMO) promises large gains over cellular deployments, but existing comparisons of different architectures often mix antenna dist…
DNN-Enabled Multi-User Beamforming for Throughput Maximization under Adjustable Fairness
Kaifeng Lu, Markus Rupp, Stefan Schwarz
Ensuring user fairness in wireless communications is a fundamental challenge, as balancing the trade-off between fairness and sum rate leads to a non-convex, multi-objective optimi…
Identification of RIS-Assisted Paths for Wireless Integrated Sensing and Communication
Zeyu Huang, Stefan Schwarz, Bashar Tahir +1
Distinguishing between reconfigurable intelligent surface (RIS) assisted paths and non-line-of-sight (NLOS) paths is a fundamental problem for RIS-assisted integrated sensing and c…
Self-Supervised and Invariant Representations for Wireless Localization
Artan Salihu, Stefan Schwarz, Markus Rupp
In this work, we present a wireless localization method that operates on self-supervised and unlabeled channel estimates. Our self-supervising method learns general-purpose channel…
Attention Aided CSI Wireless Localization
Artan Salihu, Stefan Schwarz, Markus Rupp
Deep neural networks (DNNs) have become a popular approach for wireless localization based on channel state information (CSI). A common practice is to use the raw CSI in the input…
Impact of Channel Correlation on Subspace-Based Activity Detection in Grant-Free NOMA
Bashar Tahir, Stefan Schwarz, Markus Rupp
In this paper, we consider the problem of activity detection in grant-free code-domain non-orthogonal multiple access (NOMA). We focus on performing activity detection via subspace…
