Abstract
An optical receiver including: a digital filter that performs spectral shaping on a signal; an analyzer that analyzes a spectrum waveform of the signal; a determiner that determines, based on an analysis result by the analyzer, whether the spectrum waveform of the signal is a Nyquist waveform on the basis of a Nyquist first reference; and a controller that stops the spectral shaping of the signal to be performed by the digital filter when the spectrum waveform of the signal is not the Nyquist waveform as a result of the determination by the determiner, and controls a filter coefficient of the digital filter based on the spectrum waveform of the signal when the spectrum waveform of the signal is the Nyquist waveform as the result of the determination by the determiner.
