  • Providing image rejection calibration for a receiver
    Patent number: 8265584
    Abstract: According to one embodiment, a method for updating filter values of an image canceller is provided. The method may include determining a channel-to-image (C/I) ratio between a channel signal and an image signal at the canceller input and generating a gain control value based at least in part on the C/I ratio. Then correlations between the channel signal and the image signal at the canceller's input and output can be generated, along with a gear control value based at least in part on a ratio between the correlations. In turn, one or more filters of the canceller can be updated using the control values.
