On Probabilistic Shaping of Quadrature Amplitude Modulation for the Nonlinear Fiber Channel
Tobias Fehenberger, Alex Alvarado, Georg Böcherer +1
Different aspects of probabilistic shaping for a multi-span optical communication system are studied. First, a numerical analysis of the additive white Gaussian noise (AWGN) channe…

On Achievable Rates for Long-Haul Fiber-Optic Communications
Tobias Fehenberger, Alex Alvarado, Polina Bayvel +1
Lower bounds on mutual information (MI) of long-haul optical fiber systems for hard-decision and soft-decision decoding are studied. Ready-to-use expressions to calculate the MI ar…
