Abstract:
1. A method for reducing interference that a first communication signal induces on a second communication signal via an effect, comprising the steps of: obtaining a sample of the first communication signal; producing an interference compensation signal in response to processing the obtained sample with a model of the effect, the model comprising a signal processing parameter; reducing the interference to a level in response to applying the interference compensation signal to the second communication signal; changing the reduced level of the interference in response to perturbing the signal processing parameter; performing an assessment of the change; and refining the signal processing parameter according to the assessment; wherein the step of refining the signal processing parameter further comprises processing a second sample of the second communication signal with a circuit that comprises a first electrical component and a second electrical component, and wherein the method further comprises the steps of: removing power from the first electrical component in response to an occurrence of an event; and operating the circuit with power removed from the first electrical component while power feeds the second electrical component.
