Abstract

The disclosure is directed to a mobile communication device that includes automatic gain control (AGC) circuitry. Every n samples of the broadcast signals, an energy estimate of the AGC output signal is used to calculate and update a gain control value. Instead of using all n samples occurring subsequent to a previous gain control value update, only a subset of those n samples are used. In particular the first half of the n samples may be discarded in the energy estimate calculation while only the second half of the n samples may be used.
