Uplink Cell-Free Massive MIMO OFDM with Phase Noise-Aware Channel Estimation: Separate and Shared Local Oscillators
Yibo Wu, Luca Sanguinetti, Musa Furkan Keskin +3
Cell-free massive multiple-input multiple-output (mMIMO) networks enhance coverage and spectral efficiency (SE) by distributing antennas across access points (APs) with phase coher…
Decoding Quantum LDPC Codes Using Graph Neural Networks
Vukan Ninkovic, Ognjen Kundacina, Dejan Vukobratovic +2
In this paper, we propose a novel decoding method for Quantum Low-Density Parity-Check (QLDPC) codes based on Graph Neural Networks (GNNs). Similar to the Belief Propagation (BP)-b…
Robust Performance Over Changing Intersymbol Interference Channels by Spatial Coupling
Mgeni Makambi Mashauri, Alexandre Graell i Amat, Michael Lentmaier
We show that spatially coupled low-density parity-check (LDPC) codes yield robust performance over changing intersymbol interfere (ISI) channels with optimal and suboptimal detecto…
Time vs. Frequency Domain DPD for Massive MIMO: Methods and Performance Analysis
Yibo Wu, Ulf Gustavsson, Mikko Valkama +2
The use of up to hundreds of antennas in massive multi-user (MU) multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) poses a complexity challeng…
