ABSTRACT:
Disclosed is a radio transmission device for lightening the waveform distortion of a received signal in a single-carrier transmission irrespective of a fading state. In this device, an FFT unit (103) converts a modulation signal outputted from a modulation unit (102), into a signal of a frequency range, and a repetition unit (104) repeats the frequency range signal outputted from the FFT unit (103), and arranges a plurality of frequency range signals adjacent to each other on a frequency axis. A tooth-shaped waveform forming unit (105) shapes the waveform of the frequency range signals outputted from the repetition unit (104), into a tooth-shaped waveform, and an IFFT unit (106) converts the frequency range signal outputted from the tooth-shaped waveform forming unit (105), into a signal of a time range.
