Abstract: PURPOSE: A method and a circuit for compensating a nonlinear distortion are provided, which performs a distortion compensation of a modulated signal in a broadband. CONSTITUTION: According to the nonlinear distortion compensation circuit compensating a nonlinear distortion generated during a nonlinear high power amplification in a transmitter which performs an orthogonal modulation as to a base band signal and then performs the nonlinear high power amplification, a distortion extraction part extracts a nonlinear distortion component from the amplified modulated signal. A phase feature correction part(30) corrects a phase feature so that a phase delay becomes equal per each frequency signal of the nonlinear distortion component signal in the frequency band of the extracted nonlinear distortion component signal before an orthogonal demodulation of the nonlinear distortion component. An orthogonal demodulation part(15) performs an orthogonal demodulation as to the distortion component, whose phase feature is corrected, to a base band region. And a distortion overlapping part overlaps the distortion component of a reverse phase of the distortion component in the base band region being output from the orthogonal demodulation part.
