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…
Low-Complexity Massive MIMO Tensor Precoding
Lucas N. Ribeiro, Stefan Schwarz, André L. F. de Almeida +1
We present a novel and low-complexity massive multiple-input multiple-output (MIMO) precoding strategy based on novel findings concerning the subspace separability of Rician fading…
Double-Sided Massive MIMO Transceivers for MmWave Communications
Lucas N. Ribeiro, Stefan Schwarz, André L. F. de Almeida
We propose practical transceiver structures for double-sided massive multiple-input-multiple-output (MIMO) systems. Unlike standard massive MIMO, both transmit and receive sides ar…
Versatile Mobile Communications Simulation: The Vienna 5G Link Level Simulator
Stefan Pratschner, Bashar Tahir, Ljiljana Marijanovic +5
Research and development of mobile communications systems require a detailed analysis and evaluation of novel technologies to further enhance spectral efficiency, connectivity and…
