OFDM DEMODULATION APPARATUS, OFDM DEMODULATION METHOD, OFDM DEMODULATION PROGRAM, AND RECORDING MEDIUM

摘要

PPROBLEM TO BE SOLVED: To provide an OFDM (Orthogonal Frequency Division Multiplex) demodulation apparatus which prevents a reception rate from being reduced due to frame re-synchronization that is not required. PSOLUTION: In the OFDM demodulation apparatus 100, a signal quality discrimination section 152 discriminates a signal quality of a waveform-equalized data signal on the basis of a modulation error ratio calculated by a modulation error ratio calculation section 151. A synchronization section 153e then determines whether or not frame synchronization is established based on a determination result of the signal quality on the basis of result of the signal quality discrimination unit 152, so that useless frame re-synchronization is prevented while a sufficient signal quality of an output signal is obtained.
