Abstract:
1. A method of controlling a notching mechanism in a wireless receiver, comprising: setting a current value of a notching control signal to a new value; providing the notching control signal to the notching mechanism in order to control a notch frequency of the notching mechanism; passing an incoming signal through the notching mechanism to generate a notched signal having a notch at the notch frequency; measuring a current value of a signal parameter for the notched signal; storing the current value of the notching control signal and the current value of the signal parameter in a notching database in a memory device; repeating the setting of the current value of the notching control signal, providing the notching control signal to the notching mechanism, measuring the current value of the signal parameter, and storing the current value of the notching control signal and the current value of the signal parameter, until the current value of the notching control signal has passed through a set control signal range of values; analyzing the notching database to select one of the notching control signal values that corresponds to a desired level of signal performance; and setting an operating value of the notching control signal to the selected notching control signal value.
