Patent ID: 7953179

Claim:
Communication equipment for transmitting signals of an OFDM system, comprising: a forming means for forming a plurality of OFDM signals; a peak-suppressing means of a base band for suppressing peaks of the OFDM signals based on the plurality of OFDM signals formed by the forming means; an 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; a peak-suppressing means of the intermediate frequency for suppressing peaks of the intermediate-frequency signals based on a plurality of intermediate-frequency signals converted by the IF converter means; a 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 an amplifier means for amplifying the signals after synthesized by the synthesizing, 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.
