Abstract:
A signal receiver having a gain control circuit comprising: detection means configured to form a representation of the excess amplitude during a training period of a signal received by the receiver; a first gain stimulus generator configured to generate a first gain stimulus in dependence on the excess amplitude detected by the detection means during the training period; averaging means configured to estimate the average of the signal received by the receiver during the training period; a second gain stimulus generator configured to generate a second gain stimulus in dependence on the average estimated by the averaging means during the training period; and a gain control signal generator configured to generate a gain control signal for the receiver in dependence on the first gain stimulus and the second gain stimulus.
