Radio apparatus, distortion correction device, and distortion correction method

摘要

In a radio apparatus (1), when a distortion correction coefficient, which is calculated according to a signal input to a power amplifier and a signal output from the power amplifier (2, 180, 12), is larger than a first threshold, a distortion correction coefficient corresponding to the input signal is updated to the first threshold. When the calculated distortion correction coefficient is equal to or smaller than the first threshold, the distortion correction coefficient corresponding to the input signal is updated to the calculated distortion correction coefficient.
