Uplink Beam Management for Millimeter Wave Cellular MIMO Systems with Hybrid Beamforming
George C. Alexandropoulos, Ioanna Vinieratou, Mattia Rebato +2
Hybrid analog and digital BeamForming (HBF) is one of the enabling transceiver technologies for millimeter Wave (mmWave) Multiple Input Multiple Output (MIMO) systems. This technol…
Machine Learning-aided Design of Thinned Antenna Arrays for Optimized Network Level Performance
Mattia Lecci, Paolo Testolina, Mattia Rebato +2
With the advent of millimeter wave (mmWave) communications, the combination of a detailed 5G network simulator with an accurate antenna radiation model is required to analyze the r…
Enabling Simulation-Based Optimization Through Machine Learning: A Case Study on Antenna Design
Paolo Testolina, Mattia Lecci, Mattia Rebato +5
Complex phenomena are generally modeled with sophisticated simulators that, depending on their accuracy, can be very demanding in terms of computational resources and simulation ti…
Performance Assessment of MIMO Precoding on Realistic mmWave Channels
Mattia Rebato, Luca Rose, Michele Zorzi
In this paper, the performance of multi-user Multiple-Input Multiple-Output (MIMO) systems is evaluated in terms of SINR and capacity. We focus on the case of a downlink single-cel…
A Spectrum Sharing Solution for the Efficient Use of mmWave Bands in 5G Cellular Scenarios
Mattia Rebato, Michele Zorzi
Regulators all around the world have started identifying the portions of the spectrum that will be used for the next generation of cellular networks. A band in the mmWave spectrum…
Multi-Sector and Multi-Panel Performance in 5G mmWave Cellular Networks
Mattia Rebato, Michele Polese, Michele Zorzi
The next generation of cellular networks (5G) will exploit the mmWave spectrum to increase the available capacity. Communication at such high frequencies, however, suffers from hig…
