Patent ID: 8326252

Claim:
An apparatus comprising: a signal channel path including: a first mixer to receive an intermediate frequency (IF) signal and to downconvert the IF signal to a signal channel baseband signal; a signal filter to receive a value of the signal channel baseband signal and to generate a filtered signal channel value; a first combiner to combine the signal channel baseband signal with a filtered image channel value to obtain a signal channel path output; an image channel path including: a second mixer to receive the IF signal and to downconvert the IF signal to an image channel baseband signal; an image filter to receive a value of the image channel baseband signal and to generate the filtered image channel value; a second combiner to combine the image channel baseband signal with the filtered signal channel value to obtain an image channel path output; a first controller to determine a signal strength of the signal channel baseband signal and the image channel baseband signal and to generate a step control signal based at least in part on the signal strengths; and a second controller to receive the signal channel path output and the image channel path output and to update a weighting of the image filter and the signal filter based on the signal channel path output, the image channel path output and the step control signal.
