PROBLEM TO BE SOLVED: To obtain a peak reducing circuit in which the number of repetitive processing times of peak reduction processing can be reduced.SOLUTION: A peak reducing circuit includes a peak detection unit for detecting a peak which exceeds an OFDM signal by a predetermined threshold, cancel signal generation units 19a-19n for generating a cancel signal based on the information of a peak, for each peak detected by the peak detection unit, and an adder 20 for outputting the total sum of cancel signals generated for respective peaks. The output from the adder 20 is added to the OFDM signal thus reducing the peak thereof. |
