In an OFDM transmitter, a signal processing circuit for reducing a PAPR of a modulated signal includes: a peak detector configured to detect peaks having sizes above a threshold value from an IQ baseband signal of the modulated signal and to output information on a position, a size and a phase; a memory configured to store a reference peak in time domain; a peak generator configured to generate an inverse peak signal for canceling a part of an amplitude of the IQ baseband signal from the reference peak based on the information on the position, the size and the phase; and a signal processing unit configured to add the inverse peak signal to the IQ baseband signal to constrain the amplitude of the IQ baseband signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for reducing PAPR of OFDM signal and OFDM transmitter using the same background","description":"A method for reducing a PAPR of an OFDM signal and an OFDM transmitter using the same are disclosed.
