Paper Abstract

A joint blind equalization algorithm is proposed for compensating polarization-dependent loss (PDL) and random state-of-polarization (RSOP) rotation in a Stokes vector direct detection (SV-DD) system based on a time domain extended Kalman filter (EKF) algorithm. The numerical results confirm that the algorithm has a good performance which can track fast random SOP rotation up to 1.5Mrad/s even when 3dB PDL before and after fiber link is present for high-order modulation format.
