摘要： An optical device includes a fast Fourier transform (FFT) unit, a signal noise ratio (SNR) calculation processing unit, a band selecting unit, an extension-signal creating unit, an addition unit, and an inverse fast Fourier transform (IFFT) unit. The FFT unit performs the Fourier transform on an input signal that is input from the outside. The SNR calculation processing unit calculates an SNR with respect to each of bands in the input signal. The band selecting unit selects a band of which SNR exceeds a threshold and is the maximum SNR, based on respective SNRs of the bands. The extension-signal creating unit creates an extension signal based on a signal acquired by the band selecting unit. The addition unit adds the extension signal to the input signal, and creates a band-extended signal. The IFFT unit performs the inverse fast Fourier transform on the band-extended signal, and creates an output signal.
