<p>A peak electric power suppressing apparatus capable of suppressing the peak electric power by use of easy processings without degrading the error characteristic of multi-carrier signals. In the apparatus, a modulating part (100) modulates data to be transmitted. An encoding part (110) encodes the modulated data. An S/P converting part (120) S/P converts the encoded data and outputs a plurality of sequences of parallel data as obtained by the S/P conversion to an IFFT part (130), which inverse-fast-Fourier-transforms the parallel data to produce an OFDM signal. A GI adding part (140) adds a guard interval to the OFDM signal. An electric power converting part (150) converts the electric power of the OFDM signal by use of a nonlinear function. A D/A converting part (160) D/A converts the OFDM signal as electric-power-converted. A radio transmitting part (170) amplifies the electric power of the analog signal and performs predetermined radio transmission processings such as up-conversion to transmit the signal via an antenna (180).</p> |
