Information Rates and post-FEC BER Prediction in Optical Fiber Communications
arXiv:1611.09738 · doi:10.1364/OFC.2017.Th3F.3
Abstract
Information-theoretic metrics to analyze optical fiber communications systems with binary and nonbinary soft-decision FEC are reviewed. The numerical evaluation of these metrics in both simulations and experiments is also discussed. Ready-to-use closed-form approximations are presented.
