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…
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…
On the Impact of Oscillator Phase Noise on the Uplink Performance in a Massive MIMO-OFDM System
Rajet Krishnan, M. Reza Khanzadi, N. Krishnan +4
In this work we study the effect of oscillator phase noise on the uplink performance of a massive multiple-input multiple output system. Specifically, we consider an orthogonal fre…
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…
