Graph Neural Networks for Massive MIMO Detection
Andrea Scotti, Nima N. Moghadam, Dong Liu +2
In this paper, we innovately use graph neural networks (GNNs) to learn a message-passing solution for the inference task of massive multiple multiple-input multiple-output (MIMO) d…
Belief Propagation as Fully Factorized Approximation
Dong Liu, Nima N. Moghadam, Lars K. Rasmussen +2
Belief propagation (BP) can do exact inference in loop-free graphs, but its performance could be poor in graphs with loops, and the understanding of its solution is limited. This w…
On the Energy Efficiency of MIMO Hybrid Beamforming for Millimeter Wave Systems with Nonlinear Power Amplifiers
Nima N. Moghadam, Gábor Fodor, Mats Bengtsson +1
Multiple-input multiple-output (MIMO) millimeter wave (mmWave) systems are vulnerable to hardware impairments due to operating at high frequencies and employing a large number of r…
