The present invention relates to a polarization scattering compensation device and method. The polarization scattering compensation device is used for a receiver receiving data modulated on signal in first polarization state and signal in second polarization state and transmitted by a transmitter. In the polarization scattering compensation device, a time sequence alignment unit aligns time sequences of the signal in the first polarization state and the signal in the second polarization state transmitted simultaneously; a polarization scattering estimation unit estimates a scattering coefficient of a scattering by the signal in the first polarization state on the signal in the second polarization state, and a scattering coefficient of a scattering by the signal in the second polarization state on the signal in the first polarization state, with respect to the signals after the time sequence alignment; and a polarization scattering removal unit removes the scattering by the signal in the first polarization state on the signal in the second polarization state, and the scattering by the signal in the second polarization state on the signal in the first polarization state, in accordance with the scattering coefficient of the scattering by the signal in the first polarization state on the signal in the second polarization state, and the scattering coefficient of the scattering by the signal in the second polarization state on the signal in the first polarization state. |
