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.","url_abs":"https://arxiv.org/abs/1903.12260v2","url_pdf":"https://arxiv.org/pdf/1903.12260v2.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"links_only","authors_date_abstract":"arXiv metadata, CC0 1.0 (https://info.arxiv.org/help/license), from the Kaggle arXiv metadata snapshot of 2026-09-12"},"code_links":[{"paper_slug":"advanced-digital-signal-processing-techniques","repo_url":"https://github.com/dario-pilori/dsp-library","is_official":1,"mentioned_in_paper":0,"mentioned_in_github":0,"framework":"none","reach":null}],"tasks":[],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
