4D-CMA: Enabling separation of channel compensation and polarization demultiplex

We propose a 4D-CMA feedback for butterfly filter adaptation enabling separation of channel compensation and polarization demultiplex. Using a digital polarization controller for demultiplex we demonstrate feasibility and ~10-fold speed increase compared to standard CMA.
