MRT-based Joint Unicast and Multigroup Multicast Transmission in Massive MIMO Systems
Meysam Sadeghi, Emil Björnson, Erik G. Larsson +2
We study joint unicast and multigroup multicast transmission in single-cell massive multiple-input-multiple-output (MIMO) systems, under maximum ratio transmission. For the unicast…
Nyquist-Sampling and Degrees of Freedom of Electromagnetic Fields
Andrea Pizzo, Andrea de Jesus Torres, Luca Sanguinetti +1
A signal space approach is presented to study the Nyquist sampling, number of degrees of freedom and reconstruction of an electromagnetic field under arbitrary scattering condition…
How Does Cell-Free Massive MIMO Support Multiple Federated Learning Groups?
Tung T. Vu, Hien Quoc Ngo, Thomas L. Marzetta +1
Federated learning (FL) has been considered as a promising learning framework for future machine learning systems due to its privacy preservation and communication efficiency. In b…
Fourier Plane-Wave Series Expansion for Holographic MIMO Communications
Andrea Pizzo, Luca Sanguinetti, Thomas L. Marzetta
Imagine a MIMO communication system that fully exploits the propagation characteristics offered by an electromagnetic channel and ultimately approaches the limits imposed by wirele…
Multi-point Coordination in Massive MIMO Systems with Sectorized Antennas
Shahram Shahsavari, Mehrdad Nosrati, Parisa Hassanzadeh +3
Non-cooperative cellular massive MIMO, combined with power control, is known to lead to significant improvements in per-user throughput compared with conventional LTE technology. I…
Spatial Characterization of Electromagnetic Random Channels
Andrea Pizzo, Luca Sanguinetti, Thomas L. Marzetta
The majority of stochastic channel models rely on the electromagnetic far-field assumption, which allows to decompose the channel in terms of plane waves. The far-field assumption…
