Multi-dimensional Short Blocklength Probabilistic Shaping for Digital Subcarrier Multiplexing Systems
Abdelkerim Amari, Andre Richter
We propose multi-dimensional short blocklength probabilistic shaping to increase the nonlinear tolerance gain in digital subcarrier multiplexing transmission systems and demonstrat…
Comparison of Short Blocklength Sphere Shaping and Nonlinearity Compensation in WDM Systems
Abdelkerim Amari, Lutz Lampe, O. S. Sunish Kumar +2
In optical communication systems, short blocklength probabilistic enumerative sphere shaping (ESS) provides both linear shaping gain and nonlinear tolerance. In this work, we inves…
Intra-Channel Nonlinearity Compensation Based on Second-Order Perturbation Theory
O. S. Sunish Kumar, A. Amari, O. A. Dobre +1
The first-order (FO) perturbation theory has been widely investigated to design the digital nonlinearity compensation (NLC) technique to deal with the intra-channel fiber nonlinear…
Introducing Enumerative Sphere Shaping for Optical Communication Systems with Short Blocklengths
Abdelkerim Amari, Sebastiaan Goossens, Yunus Can Gultekin +6
Probabilistic shaping based on constant composition distribution matching (CCDM) has received considerable attention as a way to increase the capacity of fiber optical communicatio…
