摘要：
A distortion compensator for compensating for distortion produced in an amplifier that amplifies a signal includes a signal level detector for detecting a level of a signal to be amplified and a distortion compensator for conducting distortion compensation based on the detection result separately for each frequency band signal of multiple frequency band signals contained in the signal to be amplified. The distortion compensator improves distortion compensation performance by reducing the effect of frequency characteristics that restrict the distortion compensation performance limit.
