Towards 6G MIMO: Massive Spatial Multiplexing, Dense Arrays, and Interplay Between Electromagnetics and Processing
Emil Björnson, Chan-Byoung Chae, Robert W. Heath +7
The increasing demand for wireless data transfer has been the driving force behind the widespread adoption of Massive MIMO (multiple-input multiple-output) technology in 5G. The ne…
Shannon Theory for Wireless Communication in a Resonant Chamber
Amritpal Singh, Thomas Marzetta
A closed electromagnetic resonant chamber (RC) is a highly favorable artificial environment for wireless communication. A pair of antennas within the chamber constitutes a two-port…
Wide-Aperture MIMO via Reflection off a Smooth Surface
Andrea Pizzo, Angel Lozano, Sundeep Rangan +1
This paper provides a deterministic channel model for a scenario where wireless connectivity is established through a reflection off a smooth planar surface of an infinite extent.…
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…
