Claim:
A polarization scattering compensation device used for a receiver receiving data modulated on a signal in first polarization state and a signal in second polarization state and transmitted by a transmitter, the polarization scattering compensation device comprising: a time sequence alignment unit to align time sequences of the signal in the first polarization state and the signal in the second polarization state which is transmitted by the transmitter simultaneously when the signal in the first polarization state is transmitted; a polarization scattering estimation unit to estimate 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 in the first polarization state and the second polarization state after the time sequence alignment; and a polarization scattering removal unit to remove 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 estimated by the polarization scattering estimation unit.
