Abstract
A distortion compensation apparatus includes distortion generating means for generating distortions to compensate for a distortion generated in an amplifier 2. The distortion generating means includes a nonlinear circuit 13 having an input/output expansion characteristic as a circuit which generates a distortion of the lowest odd order as a compensation target and also includes a nonlinear circuit 18 having an input/output saturation characteristic as a circuit which generates a distortion of another odd order as a compensation target.
Claims3
