Zusammenfassung:PROBLEM TO BE SOLVED: To accurately demodulate a reception signal of a DVB-T2 standard even if spectrum inversion occurs. SOLUTION: A maximum searcher 73 uses a P1 signal in received DVB-T2 signals, and detects the presence or absence of occurrence of spectrum inversion in the DVB-T2 signals. A spectrum inverter 74 performs spectrum inversion processing to a signal supplied from an orthogonal demodulation unit. An FFT operation unit 76, or the like demodulates the signal subjected to the spectrum inversion processing by the spectrum inverter 74 when the presence of occurrence of the spectrum inversion is detected, and demodulates a signal not subjected to the spectrum inversion processing supplied from the orthogonal demodulation unit when the absence of the spectrum inversion is detected. The present invention can be applied to, for example, a reception system for receiving the DVB-T2 signals. COPYRIGHT: (C)2011,JPO&INPIT
