In the present invention a bandwidth division timing adjustment unit (10) aligns the timing of multiple signals in a time domain, said multiple signals being obtained by dividing a received signal for each of multiple frequency bands, and then combines the multiple signals the timing of which has been aligned. A wavelength dispersion compensation unit (17) compensates wavelength dispersion of an output signal from the bandwidth division timing adjustment unit (10) for each of the multiple frequency bands.
