Abstract
A receiver for use in a cellular communication system includes a first amplifying circuit for amplifying a received signal, an attenuating circuit for selectively attenuating the amplified signal in response to a control signal, a first converting circuit for converting the attenuated signal into an intermediate frequency signal, a second amplifying circuit for amplifying the intermediate frequency signal, a limiter for limiting the amplitude of the amplified intermediate frequency signal, a second converting circuit for converting the current of the amplified intermediate frequency signal or the amplitude-limited intermediate frequency signal into a first direct voltage, a determiner for outputting the control signal for attenuating a received signal strength indicator (RSSI) of the amplified signal by a predetermined strength if the first direct voltage is greater than a predetermined reference voltage and for adding a predetermined voltage with the first direct voltage and then for outputting the added voltage as a second direct voltage, and a detector for detecting the RSSI from the second direct voltage.
