Abstract:
A peak suppressing and restoring method includes suppressing a peak of a signal, starting suppression when a suppression start value is lower than a suppression target value, using a function of a gain characteristic such that a peak amplitude value attains the suppression target value, and restoring the suppressed peak of the signal using an inverse function of the function of the gain characteristic.
