摘要： An OFDM transmitter that performs a peak reduction process in a stepwise manner on a signal sequence to be transmitted. The transmitter includes a dividing IFFT unit that divides a signal sequence into a plurality of signal sequences and IFFTs each of the signal sequences to obtain time signal sequences. Then, a first peak reduction processing unit cyclically shifts a first one of the time signal sequences by a first amount of cyclic shift obtained based on a first threshold to obtain a first cyclically shifted time signal sequence, and adds the first cyclically shifted time signal sequence and a second one of the time signal sequences. Meanwhile, a second peak reduction processing unit cyclically shifts a third one of the time signal sequences by a second amount of cyclic shift obtained based on a second threshold to obtain a second cyclically shifted time signal sequence.
