Learned Digital Back-Propagation for Dual-Polarization Dispersion Managed Systems

Published 23 May 2022 in eess.SP, cs.AI, and cs.LG | (2205.11376v1)

Abstract: Digital back-propagation (DBP) and learned DBP (LDBP) are proposed for nonlinearity mitigation in WDM dual-polarization dispersion-managed systems. LDBP achieves Q-factor improvement of 1.8 dB and 1.2 dB, respectively, over linear equalization and a variant of DBP adapted to DM systems.
