Advanced Digital Signal Processing Techniques for High-Speed Optical Communications Links

Abstract

The main topic of this thesis is the application of advanced Digital Signal Processing (DSP) techniques to high data-rate optical links. This thesis is divided in two parts: Direct-Detection systems, and Coherent systems. In the first part, it is proposed a novel bi-directional architecture for <2km Intra-DC link and a detailed analysis of self-coherent single-sideband transmission for <80km dispersion-uncompensated Inter-DC link. The second part instead focuses on Probabilistic Constellation Shaping techniques, and their impact on long-haul optical communication links.

Thesis discussed on 22 March 2019 for the conferral of the PhD degree in Electrical, Electronics and Communications Engineering at the Doctoral School of Politecnico di Torino, Italy
