Abstract
A first signal having a first polarization direction and a second signal having a second polarization direction crossing the first polarization direction are received. A phase of the second signal is controlled using a phase control signal. An interference compensation signal is generated by weighted combination on a time-series of a signal whose phase has been controlled. Weighting coefficients used for the weighted combination are set so that the interference compensation signal becomes a cross-polarization interference component of the first signal. A phase difference between the first signal and the second signal is estimated using the weighting coefficients. The phase control signal is generated using the estimated phase difference so that a phase of the first signal and the phase of the second signal become identical. The first signal is compensated for cross-polarization interference caused by the second signal using the interference compensation signal and the first signal.
