A baseband signal processing means for performing baseband processing of a received signal produces and updates a gain control signal for controlling gain used in a gain varying means. Time intervals for the update of the gain control signal are set on the basis of a rate of change over time in the power level of the received signal. As an absolute value of a slope of an amount of change in the power level of the received signal per unit time is larger, a shorter time interval for the update of the gain control signal is set. As an absolute value of a slope of an amount of change in the power level of the received signal per unit time is smaller, a longer time interval for the update of the gain control signal is set. |
