    摘要： A radio transmitter adopting the OFDM scheme is disclosed. The radio transmitter includes an amplitude measuring part for measuring the amplitude of a transmission signal on which inverse Fourier transform has been performed; a power control part for outputting, based on the result of the measurement, control signals each for adjusting the amplitude of a signal on which inverse Fourier transform has not been performed, each signal corresponding to one of plural sub-carriers; and multiple multiplying parts each for multiplying the amplitude of the signal by a multiplying number indicated by the control signal. The power control part outputs the control signal based on a product of a signal p f (n) obtained by performing Fourier transform on an output of the amplitude measuring part and the signal s f (n).
