Abstract
A signal processing apparatus according to the present disclose includes: a regulation unit configured to regulate one or both of an input signal and a calibration signal for performing calibration of transmission systems so that a difference between signal power of the input signal and signal power of the calibration signal is reduced; a compensation unit configured to perform distortion compensation for the input signal and the calibration signal; an amplifier configured to amplify the input signal and the calibration signal; and an output unit configured to output the input signal and the calibration signal that have been regulated by the regulation unit to the amplifier. Thus, there are provided the signal processing apparatus, a radio communication apparatus, a signal processing method, and a program that reduce non-linear distortion of an amplifier and distortion caused by a memory effect of the amplifier in the calibration signal.
