Patent ID: 7606544

Claim:
A receiver for processing a signal, comprising: a first amplifier circuit that is operated in association with a first gain profile; a second amplifier circuit that is operated in association with a second gain profile, wherein the first amplifier circuit and the second amplifier circuit provide relative contributions to an overall gain value of the receiver and the relative contributions to the overall gain value of the receiver change from the first amplifier circuit to the second amplifier circuit at a take-over-point, the take-over-point comprising a particular amplitude of a modulated signal; a gain control circuit, comprising: a level detector; a demodulation circuit that determines a first quality indicator associated with the modulated signal and demodulates the modulated signal to create a demodulated signal; an error correction circuit that determines a second quality indicator associated with the demodulated signal; and a processor that adjusts the first gain profile and the second gain profile by adjusting the take-over-point from a first amplitude of the modulated signal to a second amplitude of the modulated signal based at least in part upon the determined first quality indicator, only if the second quality indicator exceeds a predetermined threshold.
