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…
Near- and Far-Field Communications with Large Intelligent Surfaces
Andrea de Jesus Torres, Luca Sanguinetti, Emil Björnson
This paper studies the uplink spectral efficiency (SE) achieved by two single-antenna user equipments (UEs) communicating with a Large Intelligent Surface (LIS), defined as a plana…
URLLC with Massive MIMO: Analysis and Design at Finite Blocklength
Johan Östman, Alejandro Lancho, Giuseppe Durisi +1
The fast adoption of Massive MIMO for high-throughput communications was enabled by many research contributions mostly relying on infinite-blocklength information-theoretic bounds.…
Rayleigh Fading Modeling and Channel Hardening for Reconfigurable Intelligent Surfaces
Emil Björnson, Luca Sanguinetti
A realistic performance assessment of any wireless technology requires the use of a channel model that reflects its main characteristics. The independent and identically distribute…
Outage Analysis of Downlink URLLC in Massive MIMO systems with Power Allocation
Alexandru-Sabin Bana, Luca Sanguinetti, Elisabeth De Carvalho +1
Massive MIMO is seen as a main enabler for low latency communications, thanks to its high spatial degrees of freedom. The channel hardening and favorable propagation properties of…
A Rate Splitting Strategy for Mitigating Intra-Cell Pilot Contamination in Massive MIMO
Christo Kurisummoottil Thomas, Bruno Clerckx, Luca Sanguinetti +1
The spectral efficiency (SE) of Massive MIMO (MaMIMO) systems is affected by low quality channel estimates. Rate-Splitting (RS) has recently gained some interest in multiuser multi…
Code-domain NOMA in Massive MIMO: When is it Needed?
Mai T. P. Le, Luca Sanguinetti, Emil Björnson +1
In overloaded Massive MIMO (mMIMO) systems, wherein the number of user equipments (UEs) exceeds the number of base station antennas , it has recently been shown that non-ort…
Power Scaling Laws and Near-Field Behaviors of Massive MIMO and Intelligent Reflecting Surfaces
Emil Björnson, Luca Sanguinetti
The use of large arrays might be the solution to the capacity problems in wireless communications. The signal-to-noise ratio (SNR) grows linearly with the number of array elements…
