1. A method for reducing interference in a receiver, comprising:

  • receiving a first signal, wherein the first signal includes a desired signal and an undesired signal that results from an interfering signal being applied to a first path;

    generating a second signal, wherein generating the second signal comprises applying the interfering signal to a second path;

    processing the second signal to generate a third signal, including adjusting the second signal based on a difference between a first transfer function of the first path and a second transfer function of the second path; and

    subtracting the third signal from the first signal to reduce the undesired signal in the first signal.
