  • Receivers for mobile telephone systems
    Patent number: 5204976
    Abstract: A receiver for a mobile telephone system, the receiver having a gain control coupled to receive an input burst signal and being switchable in response to the value of a gain control signal between a plurality of gain values. A detector for detecting the amplitude of said input burst signal, an averager for storing the value of the detected amplitude and a timer operative in response to the detection of said input signal for timing a sequence of measurements of the amplitude of the input burst signal, said averager being operative to compute an average value of the amplitude and to provide a corresponding gain control signal for a subsequent time period.
