Zusammenfassung:	PROBLEM TO BE SOLVED: To correctly demodulate data even if a spectrum inversion occurs in a data communication using multicarrier.SOLUTION: A multicarrier demodulation part 16 extracts the data transmitted on a predetermined carrier from the data obtained by an FFT (Fast Fourier Transform) calculation corresponding to a SI inversion flag setting, and detects spectrum inversion occurrence by determining whether SI decoding is possible or not using the extracted data. If a spectrum inversion is detected, the spectrum inversion is compensated for by performing a frequency de-interleaving after a carrier number substitution and outputting data after swapping I-phase data and Q-phase data. The present invention can be applied to a receiving apparatus capable of multicarrier transmission.
