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…
Learning-based Remote Radio Head Selection and Localization in Distributed Antenna System
Artan Salihu, Stefan Schwarz, Markus Rupp
In this work, we consider estimating user positions in a spatially distributed antenna system (DAS) from the uplink channel state information (CSI). However, with the increased num…
Towards Scalable Uncertainty Aware DNN-based Wireless Localisation
Artan Salihu, Stefan Schwarz, Markus Rupp
Existing deep neural network (DNN) based wireless localization approaches typically do not capture uncertainty inherent in their estimates. In this work, we propose and evaluate va…
