Deep Neural Network Assisted Second-Order Perturbation-Based Nonlinearity Compensation (2105.09027v3)

Published 19 May 2021 in eess.SP

Abstract: We propose a fiber nonlinearity post-compensation technique using the DNN and the second-order perturbation theory. We achieve 1 dB Q-factor improvement for a 32 Gbaud PDM-64-QAM at 1200 km compared to the linear dispersion compensation.
