Abstract:
1. An OFDM signal receiving system for receiving an OFDM signal, comprising: a signal receiving unit configured to receive the OFDM signal and to convert the OFDM signal into a baseband OFDM signal; a time wave operation unit configured to perform a predetermined calculation on a time wave signal that is an output of the signal receiving unit; a Fourier transform unit configured to perform a Fourier transform on an output of the time wave operation unit; a frequency component extraction unit configured to extract a specific frequency component from an output of the Fourier transform unit; an inverse Fourier transform unit configured to perform an inverse Fourier transform on the frequency component extracted by the frequency component extraction unit; a reception quality measurement unit configured to measure quality of an output signal of the inverse Fourier transform unit and generate reception quality data; and a time wave control unit configured to control the time wave operation unit based on the reception quality data.
