Abstract
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 circuitinserts 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 2pieces of data including the data inserted by the carrier extension circuit, IFFT processing by an IFFT circuit, noise removal processing by a noise removal filter, and FFT processing by a FFT circuitare performed. The data inserted by the carrier extension circuitis removed from the data group outputted from the FFT circuit, and the data group after the data removal is used for interpolation in a symbol direction.
