PEAK SUPPRESSION DEVICE AND PEAK SUPPRESSION METHOD

摘要

Increase of the circuit size associated with a peak suppression process can be suppressed. Provided is a peak suppression device including: a peak determination unit which determines a peak value of a waveform of an input signal; an impulse signal generation unit which generates an impulse signal corresponding to a difference between the peak value and a predetermined value if the absolute value of the peak value is greater than the predetermined value; a multiplication unit which multiplies the generated impulse signal by a predetermined impulse response waveform so as to generate a peak suppression signal; and a subtraction unit which subtracts the peak suppression signal from the input signal.
