Adaptive Turbo Equalization of Probabilistically Shaped Constellations

Not Accessible

Your library or personal account may give you access

Abstract

Fiber nonlinearity compensation of probabilistically shaped constellations with adaptive turbo equalization is investigated for the first time. Potential for more than 100% transmission reach extension is demonstrated by combining probabilistic shaping, single-channel digital backpropagation, and adaptive turbo equalization.
