The p-waveform generator(401) generates a p-waveform having an impulse property using L-number tones out of N-number signals. The peak detector(403) detects a maximum peak of an x-signal of a time domain. The position circulation shifter(405) circulates and shifts a position of the p-waveform to a position of the maximum peak detected. The phase rotator(407) matches a phase of the p-waveform to a detected phase of the maximum peak. The scaler(409) scales a value of the p-waveform to generate a scale value c. The PAPR calculator(413) calculates a PAPR value with respect to the sum of an IFFT(Inverse Fast Fourier Transfom) output signal and the scale value c. The controller(415) feedbacks the calculated PAPR value in order to make it have a value less than a predetermined PAPR value.
