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…
Outage Analysis of Uplink IRS-Assisted NOMA under Elements Splitting
Bashar Tahir, Stefan Schwarz, Markus Rupp
In this paper, we investigate the outage performance of an intelligent reflecting surface (IRS)-assisted non-orthogonal multiple access (NOMA) uplink, in which a group of the surfa…
RIS-Assisted Code-Domain MIMO-NOMA
Bashar Tahir, Stefan Schwarz, Markus Rupp
We consider the combination of uplink code-domain non-orthogonal multiple access (NOMA) with massive multiple-input multiple-output (MIMO) and reconfigurable intelligent surfaces (…
Low-Complexity Zero-Forcing Precoding for XL-MIMO Transmissions
Lucas N. Ribeiro, Stefan Schwarz, Martin Haardt
Deploying antenna arrays with an asymptotically large aperture will be central to achieving the theoretical gains of massive MIMO in beyond-5G systems. Such extra-large MIMO (XL-MI…
