A peak power suppressing apparatus for suppressing the peak power with simple process without deteriorating the error characteristics of multi-carrier signals. In this apparatus, a modulation section ( 100 ) modulates transmission data. A coding section ( 110 ) codes the modulated data. An S/P conversion section ( 120 ) S/P converts the coded data and outputs the obtained parallel data of a plurality of sequences to an IFFT section ( 130 ). The IFFT section ( 130 ) performs inverse fast Fourier transform on the parallel data to generate an OFDM signal. A GI adding section ( 140 ) adds a guard interval to the OFDM signal. A power conversion section ( 150 ) converts the power of the OFDM signal using the non-linear function. AD/A conversion section ( 160 ) D/A converts the OFDM signal after the power conversion. A wireless transmission section ( 170 ) amplifies the power of the analog signal, performs a predetermined wireless transmission process such as up conversion and transmits the result via an antenna ( 180 ).
