  • Publication number: 20240121007
    Abstract: A distortion compensation filter whose filter coefficient is adaptively controlled compensates for a distortion included in a reception signal obtained by performing coherent reception of a signal transmitted from a transmitter in a receiver. A group delay ripple calculation device calculates a group delay included in the reception signal based on a filter coefficient of a distortion compensation filter and calculates group delay ripple from the calculated group delay. The feedback calculation unit calculates a phase response based on the calculated group delay ripple. The feedback calculation unit feeds the calculated phase response back to one or more filters having a phase compensation function disposed in a stage before an adaptive equalization filter included in the receiver, and causes one or more filters to at least partially compensate for the group delay ripple.
