A signal transmitted from a base station is received by a receiver. The received signal is supplied to an AGC amplifier and is then supplied to a demodulator, so that the signal is demodulated into baseband signals. The baseband signals are supplied to a baseband signal processor. The baseband signals are also processed through an instantaneous received power calculator, an average received power calculator, and a feedback AGC code generator to produce an AGC signal. The gain of the AGC amplifier is controlled based on the AGC signal. A fading pitch measuring device measures a fading pitch from the instantaneous power calculated by the instantaneous received power calculator. The average received power calculator changes averaging time required to calculate average received power depending on the measured fading pitch.
