Advanced Digital Signal Processing and Coding for Multi-Tb\/s Optical Transport [From the Guest Editors]

The articles in this special section aims to highlight diverse recent advances in digital signal processing (DSP)and coding, enabling TbE and multi-TbE optical transport while addressing bandwidth and energy constraints. The addressed topics range from sophisticated modulation and coding schemes to advanced detection schemes. The multi-Tb/s optical transports over either singlemode fibers or few-mode/few-core fibers are also topics covered in this special issue. The main technologies covered by this special issue comprise multiple-input, multiple-output (MIMO) signal processing, advanced multilevel and multidimensional modulation schemes, advanced multiplexing schemes, signal processing for superchannel transmission, advanced DSP for signal detection and equalization, and advanced coding, all aiming at achieving multi-Tb/s optical transports.
