Architectures and Key Technical Challenges for 5G Systems Incorporating Satellites
A. Guidotti, A. Vanelli-Coralli, M. Conti +10
Satellite Communication systems are a promising solution to extend and complement terrestrial networks in unserved or under-served areas. This aspect is reflected by recent commerc…
LTE-based Satellite Communications in LEO Mega-Constellations
A. Guidotti, A. Vanelli-Coralli, T. Foggi +5
The integration of satellite and terrestrial networks is a promising solution for extending broadband coverage to areas not connected to a terrestrial infrastructure, as also demon…
Single-Carrier Modulation versus OFDM for Millimeter-Wave Wireless MIMO
Stefano Buzzi, Carmen D'Andrea, Tommaso Foggi +2
This paper presents results on the achievable spectral efficiency and on the energy efficiency for a wireless multiple-input-multiple-output (MIMO) link operating at millimeter wav…
Integration of 5G Technologies in LEO Mega-Constellations
Alessandro Guidotti, Alessandro Vanelli-Coralli, Oltjon Kodheli +2
3GPP is finalising the first release of the 5G New Radio physical layer. To cope with the demanding 5G requirements on global connectivity and large throughput, Satellite Communica…
Spectral Efficiency of MIMO Millimeter-Wave Links with Single-Carrier Modulation for 5G Networks
Stefano Buzzi, Carmen D'Andrea, Tommaso Foggi +2
Future wireless networks will extensively rely upon bandwidths centered on carrier frequencies larger than 10GHz. Indeed, recent research has shown that, despite the large path-los…
Spectral Efficiency Optimization in Flexi-Grid Long-Haul Optical Systems
Tommaso Foggi, Giulio Colavolpe, Alberto Bononi +1
Flexible grid optical networks allow a better exploitation of fiber capacity, by enabling a denser frequency allocation. A tighter channel spacing, however, requires narrower filte…
Optical Time-Frequency Packing: Principles, Design, Implementation, and Experimental Demonstration
Marco Secondini, Tommaso Foggi, Francesco Fresi +7
Time-frequency packing (TFP) transmission provides the highest achievable spectral efficiency with a constrained symbol alphabet and detector complexity. In this work, the applicat…
Time-Frequency Packing for High Capacity Coherent Optical Links
Giulio Colavolpe, Tommaso Foggi
We consider realistic long-haul optical links, with linear and nonlinear impairments, and investigate the application of time-frequency packing with low-order constellations as a p…
