In this work, we propose to use various artificial neural network (ANN) structures for modeling and compensation of intra- and inter-subcarrier fiber nonlinear interference in digital subcarrier multiplexing (DSCM) optical transmission systems.

We propose a transmitter skew calibration based on direct detection of coherent signals with estimation errors of +/-0. 2ps, providing a reliable, accurate and low-cost scheme to calibrate skew for coherent transceivers.
