On the use of PN Ranging with High-rate Spectrally-efficient Modulations
Barbara Ripani, Andrea Modenini, Roberto Garello +2
In this paper, we study the feasibility of coupling the PN ranging with filtered high-order modulations, and investigate the simultaneous demodulation of a high-rate telemetry stre…
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…
Multiuser Detection in Multibeam Satellite Systems: Theoretical Analysis and Practical Schemes
Giulio Colavolpe, Andrea Modenini, Amina Piemontese +1
We consider the rates achievable by a user in a multibeam satellite system for unicast applications, and propose alternatives to the conventional single-user symbol-by-symbol detec…
On the Use of Multiple Satellites to Improve the Spectral Efficiency of Broadcast Transmissions
Andrea Modenini, Alessandro Ugolini, Amina Piemontese +1
We consider the use of multiple co-located satellites to improve the spectral efficiency of broadcast transmissions. In particular, we assume that two satellites transmit on overla…
On the Application of Multiuser Detection in Multibeam Satellite Systems
Giulio Colavolpe, Andrea Modenini, Amina Piemontese +1
We study the achievable rates by a single user in multibeam satellite scenarios. We show alternatives to the conventional symbol-by-symbol detection applied at user terminals. Sing…
Modulation Formats and Waveforms for the Physical Layer of 5G Wireless Networks: Who Will be the Heir of OFDM?
Paolo Banelli, Stefano Buzzi, Giulio Colavolpe +3
5G cellular communications promise to deliver the gigabit experience to mobile users, with a capacity increase of up to three orders of magnitude with respect to current LTE system…
Advanced transceivers for spectrally-efficient communications
Andrea Modenini
In this thesis, we will consider techniques to improve the spectral efficiency of digital communication systems, operating on the whole transceiver scheme. First, we will focus on…
Optimal Transmit Filters for ISI Channels under Channel Shortening Detection
Andrea Modenini, Fredrik Rusek, Giulio Colavolpe
We consider channels affected by intersymbol interference with reduced-complexity, mutual information optimized, channel-shortening detection. For such settings, we optimize the tr…
Improving the Spectral Efficiency of Nonlinear Satellite Systems through Time-Frequency Packing and Advanced Processing
Amina Piemontese, Andrea Modenini, Giulio Colavolpe +1
We consider realistic satellite communications systems for broadband and broadcasting applications, based on frequency-division-multiplexed linear modulations, where spectral effic…
