<p>An amplification device includes an amplifier (4) for amplifying a signal and compensates distortion caused by the amplifier (4). The device can be used even after the distortion component contained in the amplified signal after the distortion compensation becomes large. Distortion component size detection means (7, 8) detect the size of the distortion component generated in the amplifier (4) contained in the signal amplified by the amplifier (4) after the distortion compensation. When the size of the distortion component detected exceeds a predetermined threshold value, amplified signal level lowering control means (9, 1) perform control so as to lower the level of the signal amplified by the amplifier (4). In distortion compensation, pre-distortion means (3) generates distortion in the signal before amplified by the amplifier (4) and the pre-distortion control means (9) controls the distortion generated by the pre-distortion means (3) according to the size of the distortion component detected.</p> |
