Patent ID: 8537039

Claim:
A distortion correcting device comprising: a first A/D converter configured to A/D convert a first input signal to obtain a first converted signal; a second A/D converter configured to A/D convert a second input signal to obtain a second converted signal, wherein the second input signal is a signal obtained by reducing an amplitude of the first input signal, or the first input signal is a signal obtained by increasing an amplitude of the second input signal; an exponentiator configured to obtain an exponential signal by raising the second converted signal to an n-th power (“n” is an integer of 2 or more); an adaptive correlation controller configured to carry out adaptive correlation control based on the exponential signal and the second converted signal to generate a distortion signal that is an n-th power component contained in the exponential signal; and a distortion remover configured to remove the distortion signal from the first converted signal.
