Receiving device, integrated circuit and a receiving method

Carrier extension circuit 341, for the data group composed of data indicating channel characteristics of the scattered pilot signal positions whose phases are aligned by dividing the scattered pilot signal during transmission of the scattered pilot signals included in the OFDM signal, together with the data of the same value as the value of the data of the lower end on the outside of the lower end of the band is added, it adds data having the same value as the value of the data of the upper end outside of the upper end of the band. Data group composed of The added data by the carrier extension circuit 341 from the data group outputted from the FFT circuit 344 is removed, using the data group after the removal in the symbol direction interpolation.
