Capacity Scaling of Massive MIMO in Strong Spatial Correlation Regimes
Junyoung Nam, Giuseppe Caire, Merouane Debbah +1
This paper investigates the capacity scaling of multicell massive MIMO systems in the presence of spatially correlated fading. In particular, we focus on the strong spatial correla…
Fast HARQ over Finite Blocklength Codes: A Technique for Low-Latency Reliable Communication
Behrooz Makki, Tommy Svensson, Giuseppe Caire +1
This paper studies the performance of delay-constrained hybrid automatic repeat request HARQ protocols. Particularly, we propose a fast HARQ protocol where, to increase the end-to-…
On-the-fly Large-scale Channel-Gain Estimation for Massive Antenna-Array Base Stations
Chenwei Wang, Ozgun Y. Bursalioglu, Haralabos Papadopoulos +1
We propose a novel scheme for estimating the large-scale gains of the channels between user terminals (UTs) and base stations (BSs) in a cellular system. The scheme leverages TDD o…
On the Fundamental Limits of Fog-RAN Cache-aided Networks with Downlink and Sidelink Communications
Kai Wan, Daniela Tuninetti, Mingyue Ji +1
Maddah-Ali and Niesen (MAN) in 2014 showed that coded caching in single bottleneck-link broadcast networks allows serving an arbitrarily large number of cache-equipped users with a…
Fully-Connected vs. Sub-Connected Hybrid Precoding Architectures for mmWave MU-MIMO
Xiaoshen Song, Thomas Kühne, Giuseppe Caire
Hybrid digital analog (HDA) beamforming has attracted considerable attention in practical implementation of millimeter wave (mmWave) multiuser multiple-input multiple-output (MU-MI…
Multiple Measurement Vectors Problem: A Decoupling Property and its Applications
Saeid Haghighatshoar, Giuseppe Caire
We study a Compressed Sensing (CS) problem known as Multiple Measurement Vectors (MMV) problem, which arises in joint estimation of multiple signal realizations when the signal sam…
