Nonlinear tolerant super-Gaussian distribution for probabilistic shaping modulation

Abstract:

Consistent with the present disclosure, codewords indicative of a super Gaussian distribution may be encoded and decoded using the encoders and decoders disclosed herein. Based on such codewords, symbols may be transmitted in accordance or in conformance with a super Gaussian distribution to tailor the SE of an optical signal or subcarrier for a given link having non-linear degradations and shaping gain. Such tailed SE may not be achievable with a Gaussian symbol transmission probability distribution.
