Patent ID: 7978773

Claim:
A receiver comprising: a gain section adapted to generate, based on a gain control value, an output signal from one or more received signals; a detector adapted to generate an intensity value in response to the output signal; a demodulator, for each received signal, adapted to demodulate the output signal into a corresponding demodulated signal having an amplitude; a scalar, for each demodulated signal, adapted to scale the amplitude of the corresponding demodulated signal based on a corresponding scalar control value; and a controller adapted to generate and adaptively change the gain control value and each scalar control value based on changes in the intensity value, wherein the controller is further adapted to delay a change of at least one of the scalar control values based on at least one processing delay associated with generating the corresponding demodulated signal, wherein: the receiver is adapted to receive two or more received signals; the receiver comprises two or more demodulators and two or more scalars corresponding to the two or more received signals; the controller is adapted to delay the change of each scalar control value based on the at least one processing delay associated with the generation of the corresponding demodulated signal; and the controller is adapted to delay the change of each scalar control value to coincide in time with a change in the corresponding demodulated signal resulting from an earlier change in the intensity value.
