摘要
Distortion compensation circuitHas a first distortion compensation characteristic to compensate for the first distortion occurring in the output of the amplifier;A first distortion compensation circuit for compensating the first distortion andHaving a second distortion compensation characteristic to compensate for the second distortion occurring at the output of the amplifier;A second distortion compensation circuit for compensating the second distortionAn update section for updating the second distortion compensation characteristic andEquipped withThe first distortion isIncluding nonlinear distortion and memory effect distortionThe second distortion isThe first time distortion is faster than the first strain.The update sectionThe second distortion compensation characteristic is updated at a frequency higher than that of the first distortion compensation characteristic.
