title: Kalman filter carrier and polarization-state tracking.
abstract: Application of Kalman filtering with a novel nearest-symbol constraint enables dynamic tracking of carrier phase and polarization state. Thereby, the proposed Kalman filter accomplishes demodulation of optical polarization-multiplexed complex modulation format signals.
