PURPOSE:To prevent a change in the distortion of an output signal even when a signal level is changed by controlling the distortion compensation of a distortion compensation means in response to an AGC voltage in using the signal of a distortion component formed from an input signal so as to compensate the distortion in the input signal. CONSTITUTION:An AGC voltage generating means 101 in a radio equipment detects the level of a pilot signal in the input signal to generate the AGC voltage. The radio equipment controls the gain of an amplifier in response to the AGC voltage so as to stabilize an output signal level. A distortion compensation means 102 generates the signal of distortion component from the input signal and the distortion signal compensates the distortion in the input signal. In applying the distortion compensation, a control means 103 controls the distortion compensation in the means 102 to be changed in response to the AGC signal generated in the means 101. Thus, even if the signal level is fluctuated by fading and the cross modulation distortion in the signal is fluctuated, the change in the distortion in the output is prevented.
