ABSTRACT:
In the conventional peak factor reduction technique, since the signal has been changed over broad time width before and behind the peak amplitude, the deterioration in signal quality has been great. Through the use of a compensating signal having impulse property that is generated on the peak amplitude, subtraction from the peak amplitude will be performed. Thereby, since it is possible to reduce the deterioration in signal quality that occurs when reducing the peak factor, the peak factor reduction effect can be further enhanced in the same deterioration in signal quality as the conventional one.
