Abstract
A plurality of target values for generating a gain control signal are provided such that switching is performed between the target values with a baseband signal processing unit. Specifically, the baseband signal processing unit monitors the state of a received signal to select an appropriate one of the target values based on the monitoring result. The selected target value is compared with a received power amount to generate the gain control signal. When saturation occurs at input ends of A/D converters for digital processing of the received signal, the target value is switched to the next lower target value. Thus, even when the received signal includes an interference wave in addition to a desired wave, saturation at the input ends of the A/D converters due to the interference wave is prevented, thereby making it possible to maintain favorable reception characteristics and suppression of an increased bit error rate in digital communication.
