Holographic MIMO Communications: What is the benefit of closely spaced antennas?
Antonio Alberto D'Amico, Luca Sanguinetti
Holographic MIMO refers to a (possibly large) array with a large number of individually controlled and densely deployed antennas. The objective of this paper is to provide further…
DFT-Based Channel Estimation for Holographic MIMO
Antonio Alberto D'Amico, Giacomo Bacci, Luca Sanguinetti
Holographic MIMO (hMIMO) systems with a massive number of individually controlled antennas N make minimum mean square error (MMSE) channel estimation particularly challenging, due…
Random Access in Uplink Massive MIMO Systems: How to exploit asynchronicity and excess antennas
Luca Sanguinetti, Antonio A. D'Amico, Michele Morelli +1
Massive MIMO systems, where the base stations are equipped with hundreds of antennas, are an attractive way to handle the rapid growth of data traffic. As the number of users incre…
Power Allocation in Two-Hop Amplify-and-Forward MIMO Relay Systems with QoS requirements
Luca Sanguinetti, Antonio A. D'Amico
The problem of minimizing the total power consumption while satisfying different quality-of-service (QoS) requirements in a two-hop multiple-input multiple-output network with a si…
A Tutorial on the Optimization of Amplify-and-Forward MIMO Relay Systems
Luca Sanguinetti, Antonio A. D'Amico, Yue Rong
The remarkable promise of multiple-input multiple-output (MIMO) wireless channels has motivated an intense research activity to characterize the theoretical and practical issues as…
