Co-existence Between a Radar System and a Massive MIMO Wireless Cellular System
Stefano Buzzi, Marco Lops, Carmen D'Andrea +1
In this paper we consider the uplink of a massive MIMO communication system using 5G New Radio-compliant multiple access, which is to co-exist with a radar system using the same fr…
Energy-Efficient Downlink Power Control in mmWave Cell-Free and User-Centric Massive MIMO
Mario Alonzo, Stefano Buzzi, Alessio Zappone
This paper considers cell-free and user-centric approaches for coverage improvement in wireless cellular systems operating at millimeter wave frequencies, and proposes downlink pow…
User-Centric 5G Cellular Networks: Resource Allocation and Comparison with the Cell-Free Massive MIMO Approach
Stefano Buzzi, Carmen D'Andrea, Alessio Zappone
Recently, the so-called cell-free (CF) Massive MIMO architecture has been introduced, wherein a very large number of distributed access points (APs) simultaneously and jointly serv…
Massive MIMO in Sub-6 GHz and mmWave: Physical, Practical, and Use-Case Differences
Emil Björnson, Liesbet Van der Perre, Stefano Buzzi +1
The use of base stations (BSs) and access points (APs) with a large number of antennas, called Massive MIMO (multiple-input multiple-output), is a key technology for increasing the…
Subspace Tracking and Least Squares Approaches to Channel Estimation in Millimeter Wave Multiuser MIMO
Stefano Buzzi, Carmen D'Andrea
The problem of MIMO channel estimation at millimeter wave frequencies, both in a single-user and in a multi-user setting, is tackled in this paper. Using a subspace approach, we de…
