Communication equipment

A communication equipment for transmitting signals of an OFDM system, comprising:

• forming means for forming a plurality of OFDM signals;
• peak-suppressing means of a base band for suppressing each of peaks of the OFDM signals based on the plurality of OFDM signals formed by the forming means;
• IF converter means for converting each of the OFDM signals of which the peaks are suppressed by the peak-suppressing means of the base band into intermediate-frequency signals;
• peak-suppressing means of the intermediate frequency for suppressing each of peaks of the intermediate-frequency signals based on a plurality of intermediate-frequency signals converted by the IF converter means;
• synthesizing means for synthesizing the plurality of intermediate-frequency signals of which the peaks are suppressed by the peak-suppressing means of the intermediate frequency;
• and
• amplifier means for amplifying the signals after synthesized by the synthesizing means;
• wherein,
• the peak-suppressing means of the base band suppresses the peaks with the synthesized value of absolute values of the OFDM signals as an estimated peak value;
• and
• the peak-suppressing means of the intermediate frequency suppresses the peaks with the absolute value of the result of synthesizing the plurality of intermediate-frequency signals as an estimated peak value.
