Line-of-Sight MIMO via Reflection From a Smooth Surface

Andrea Pizzo, Angel Lozano, Sundeep Rangan +1

We provide a deterministic channel model for a scenario where wireless connectivity is established through a reflection from a planar smooth surface of an infinite extent. The deve…

Coupling Matrix-based Beamforming for Superdirective Antenna Arrays

Liangcheng Han, Haifan Yin, Thomas L. Marzetta

In most multiple-input multiple-output (MIMO) communication systems, e.g., Massive MIMO, the antenna spacing is generally no less than half a wavelength. It helps to reduce the mut…

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…

Holographic MIMO Communications Under Spatially-Stationary Scattering

Andrea Pizzo, Thomas Marzetta, Luca Sanguinetti

Holographic MIMO is a spatially-constrained MIMO system with a massive number of antennas, possibly thought of, in its ultimate form, as a spatially-continuous electromagnetic aper…

Multiuser MIMO with Large Intelligent Surfaces: Communication Model and Transmit Design

Robin Jess Williams, Pablo Ramírez-Espinosa, Elisabeth de Carvalho +1

This paper proposes a communication model for multiuser multiple-input multiple-output (MIMO) systems based on large intelligent surfaces (LIS), where the LIS is modeled as a colle…
