Abstract:
A circuit (100) is provided for notching an incoming wireless signal. The circuit comprises: a notching mechanism (110) for receiving an incoming signal and generating a notched signal having reduced power at the notch frequency (320), the notch frequency being adjustable in response to a notching control signal; a signal parameter detector (165, 170, 175, 180, 185) for detecting a signal parameter of the notched signal (325); a controller (155) for receiving the signal parameter and for generating the notching control signal (315), the controller being configured to vary the signal parameter within a notching control signal range (340); and a memory (160) for storing the signal parameter and the notching control signal received from the controller in a notching database (330). The controller is configured to analyze the notching database to determine an optimal notching control signal to achieve a desired level of signal performance (345).
