A demodulation apparatus includes selectors (15r, 15i) for selecting designated data from data of N points outputted from a Fast Fourier-transform circuit (13) and previously-prepared 0 data and outputting the selected data as data of a plurality of series, output order data generators (16, 17) for designating data selected by the selectors and a decoder (20) for decoding data based on data of a plurality of series outputted from the selectors. An interleaved and punctured OFDM-modulated signal can be demodulated by a simple arrangement and in a short period of time.
