Adaptive Turbo Equalization for Nonlinearity Compensation in WDM Systems

Edson Porto da Silva, Metodi Plamenov Yankov

In this paper, the performance of adaptive turbo equalization for nonlinearity compensation (NLC) is investigated. A turbo equalization scheme is proposed where a recursive least-s…

Gradient-free training of autoencoders for non-differentiable communication channels

Ognjen Jovanovic, Metodi Plamenov Yankov, Francesco Da Ros +1

Training of autoencoders using the back-propagation algorithm is challenging for non-differential channel models or in an experimental environment where gradients cannot be compute…

Power Evolution Prediction and Optimization in a Multi-span System Based on Component-wise System Modeling

Metodi P. Yankov, Uiara Celine de Moura, Francesco Da Ros

Cascades of a machine learning-based EDFA gain model trained on a single physical device and a fully differentiable stimulated Raman scattering fiber model are used to predict and…

Machine learning-based EDFA Gain Model Generalizable to Multiple Physical Devices

Francesco Da Ros, Uiara Celine de Moura, Metodi P. Yankov

We report a neural-network based erbium-doped fiber amplifier (EDFA) gain model built from experimental measurements. The model shows low gain-prediction error for both the same de…

Perturbation-based FEC-assisted Iterative Nonlinearity Compensation for WDM Systems

Edson P. da Silva, Metodi P. Yankov, Francesco Da Ros +2

A perturbation-based nonlinear compensation scheme assisted by a feedback from the forward error correction (FEC) decoder is numerically and experimentally investigated. It is show…
