RECEIVING APPARATUS, INTEGRATED CIRCUIT AND RECEIVING METHOD

摘要

For a data group composed of pieces of data each indicating channel characteristics of a scattered pilot signal position whose phase is adjusted by dividing scattered pilot signals included in an OFDM signal by a scattered pilot signal at the time of transmission, a carrier extension circuit 341 inserts data having a same value as a value of data of a lower end into an outside of the lower end of a band, and inserts data having a same value as a value of data of an upper end into an outside of the upper end of the band. On the data group composed of 2 N pieces of data including the data inserted by the carrier extension circuit 341, IFFT processing by an IFFT circuit 342, noise removal processing by a noise removal filter 343, and FFT processing by a FFT circuit 344 are performed. The data inserted by the carrier extension circuit 341 is removed from the data group outputted from the FFT circuit 344, and the data group after the data removal is used for interpolation in a symbol direction.
