摘要： A technique wherein when signals, the modulation schemes of which are different, are to be combined, performing the peak suppression using amounts of the respective modulation schemes can effectively reduce the PAPR of a resulting combined signal. A peak suppressing method for use in a peak suppressing circuit, which combines input signals of different modulation schemes in a time domain to provide a combined signal, comprises detecting, as a peak, that portion of the combined signal which excesses a threshold value to generate a peak signal in accordance with the peak; converting the peak signal into a frequency domain signal and then dividing it into signals originating from the input signals to use these input-signal-originated signals as respective suppression signals; and adding, to the input signals, the suppression signals having different suppression amounts for the respective modulation schemes, thereby performing the peak suppression.
