A pilot signal is transmitted with a predetermined frequency band and a data signal is transmitted with a partial band of the frequency band, and the pilot signal and the data signal to be transmitted with at least the partial band, are controlled its waveform to have the same waveforms in a frequency domain. Thus, in the case of controlling waveforms of the pilot signal and the data signal which have different occupied bands, it is possible to, in a portion of the occupied band for the data signal, avoid the mapping of a low-quality pilot signal or the like, enhance the data signal demodulation capability and improve the data signal reception characteristic while suppressing PAPR.
