Shaped Four-Dimensional Modulation Formats for Optical Fiber Communication Systems

Signal Processing 2021-12-24 v1

Abstract

We review the design of multidimensional modulations by maximizing generalized mutual information and compare the maximum transmission reach of recently introduced 4D formats. A model-based optimization for nonlinear-tolerant 4D modulations is also discussed.
