<p>An error between the power of an input signal, which is input to a power amplifier (2, 180, 12), and the power of an output signal, which is output from the power amplifier (2, 180, 12), is calculated. The calculated error is normalized according to the power of the input signal or the power of the output signal. A distortion correction coefficient, which is stored in a predetermined storage unit (3, 131, 14) in association with the power of the input signal, is updated using the normalized error.</p> |
