<p>In a radio communication system and method for controlling a gain of a receiver portion of the system, a plurality of band-pass filters are provided, each band-pass filter allowing signals lying within a particular one of a plurality of distinct frequency bands to pass through the filter. A selector switch, having an input and a plurality of outputs connected to the plurality of band-pass filters, is provided, the selector switch delivering a received signal at the input to one of the plurality of band-pass filters via a selected one of the plurality of outputs connected to the one of the plurality of band-pass filters. A control unit controls switching of the selector switch in accordance with both a specified frequency contained in the received signal and a receiving level of the received signal, so that the input of the selector switch is connected to the selected one of the plurality of outputs so as to pass the received signal through the one of the plurality of band-pass filters. <IMAGE></p> |
