Abstract:
A radio transmission device capable of improving channel estimation precision for each frequency. In this device, an FFT unit (103) subjects a data signal to a Fourier transformation. A signal substitution unit (108) substitutes the frequency component of a portion of a plurality of frequency components composing the Fourier-transformed data signal, for a pilot signal. An IFFT unit (109) subjects the data signal, the frequency component of which has been partially substituted for the pilot signal, to an inverse Fourier transformation. A transmission RF unit (111) transmits the inversely Fourier-transformed data signal on a single carrier.
