Optimization of Probabilistic Shaping for Nonlinear Fiber Channels with Non-Gaussian Noise

Optimization of Probabilistic Shaping for Nonlinear Fiber Channels with Non-Gaussian Noise

Probabilistic constellation shaping is investigated in the context of nonlinear fiber optic communication channels. Based on a general framework, different link types are considered—1. dispersion-managed channels, 2. unrepeatered transmission channels and 3. ideal distributed Raman amplified channel...
