A signal receiving unit receives the OFDM signal and to convert the OFDM signal into a baseband OFDM signal. A time wave operation unit performs a predetermined calculation on a time wave signal that is an output of the signal receiving unit. A Fourier transform unit performs a Fourier transform on an output of the time wave operation unit. A frequency component extraction unit extracts a specific frequency component from an output of the Fourier transform unit. An inverse Fourier transform unit performs an inverse Fourier transform on the frequency component extracted by the frequency component extraction unit. A reception quality measurement unit measures quality of an output signal of the inverse Fourier transform unit and generate reception quality data. A time wave control unit controls the time wave operation unit based on the reception quality data. |
