Patent ID: 7769357

Claim:
A method for processing one or more received signals of a plurality of possible received signals, the method comprising: (a) generating, based on a gain control signal, an output signal from the one or more received signals; (b) generating an intensity value in response to the output signal; (c) characterizing each of the possible received signals using a demodulator corresponding to the possible received signal; (d) selecting a setpoint value from a plurality of setpoint values in response to the characterizations of step (c), wherein each of the plurality of setpoint values corresponds to a different one of a plurality of possible combinations of the plurality of possible received signals, wherein the plurality of possible combinations includes at least one combination having two or more of the possible received signals; and (e) adaptively updating the gain control signal based on changes in the intensity value, wherein updates in the gain control signal result in the intensity value approximating the setpoint value.
