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…
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…
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…
Analysis of Uplink IRS-Assisted NOMA under Nakagami-m Fading via Moments Matching
Bashar Tahir, Stefan Schwarz, Markus Rupp
This letter investigates the uplink outage performance of intelligent reflecting surface (IRS)-assisted non-orthogonal multiple access (NOMA). We consider the general case where al…
Recursive CSI Quantization of Time-Correlated MIMO Channels by Deep Learning Classification
Stefan Schwarz
In frequency division duplex (FDD) multiple-input multiple-output (MIMO) wireless communications, limited channel state information (CSI) feedback is a central tool to support adva…
