Perturbation-Assisted DBP for Nonlinear Compensation in Polarization Multiplexed Systems

We investigate an improved digital back propagation (DBP) method based on a multi-stage perturbation theory to compensate for nonlinear impairments in fiber optic links. In the standard DBP, the nonlinear operation only calculates the phase shift based on the power of the current signal sample. In t...
