Patent Number: 6,480,705

Title: Distortion compensation method and wireless communication apparatus

Abstract: An apparatus and method for distortion compensation of a high frequency power amplification section wherein a finite difference between envelopes of input and output signals of an amplifier of an object of distortion compensation is detected, and variation of a temperature and other parameters is suppressed using a component which originates from an offset of the finite difference. Further, a component of the finite difference which originates from the distortion is added to the input signal of the amplifier to effect distortion compensation.
