Abstract
An optical signal processing circuit () includes: an FDE-MIMO equalizer () configured to generate, based on continuous subcarrier signals including a target subcarrier signal in an optical multicarrier signal to be received, the continuous subcarrier signals that have been subjected to frequency-domain MIMO equalization processing; and a TDE-MIMO equalizer () configured to generate, based on the continuous subcarrier signals that have been subjected to the frequency-domain MIMO equalization processing, the target subcarrier signal that has been subjected to time-domain MIMO equalization processing.
