Abstract
A receiver for a mobile telephone system operating in a Time Division Multiple Access (TDMA) system, includes a gain control circuit coupled to receive an input signal, the circuit being switchable under the control of digital control signals between three gain or attenuation levels. An equalizer is coupled to receive the output signal from the gain control circuit. A signal strength unit determines the value of the received signals and provides the digital control signals so as to set the gain or attenuation level constant for a time slot of the TDMA system. The signal strength unit records the determined signal value so as to set the level of said gain control circuit prior to a predetermined time slot based upon measurements made during a preceding time period.
