MULTI-CARRIER TRANSMITTER

摘要

PROBLEM TO BE SOLVED: To provide a multi-carrier transmitter that reduces deterioration in an error rate characteristic due to distortion in a multi-carrier signal caused in the case of clipping and reduces deterioration in the error rate characteristic caused by decrease in a power level caused when the multi-carrier signals are uniformly suppressed so as to suppress a peak voltage. SOLUTION: An IDFT section 103 applies OFDM modulation to transmission data to generate an OFDM signal, a peak detection circuit 106 decides the necessity of suppression of a generated multi-carrier signal, a uniform suppression circuit 107 uniformly suppresses the multi-carrier signals whose suppression is decided to be required and a clipping circuit 108 clips a peak voltage part so as to suppress a peak voltage.
