Patent ID: 8724731

Claim:
A method for determining a noise cancellation control setting for generating an interference compensation signal, the method comprising: (a) generating the interference compensation signal based at least on the control setting, wherein the control setting comprises an in-phase setting and a quadrature phase setting; (b) applying the interference compensation signal to an input signal path of a receiver; (c) receiving a feedback signal comprising a feedback value indicative of a level of interference imposed on the input signal path; (d) storing the feedback value and the control setting; (e) adjusting, by the controller, the control setting; (f) repeating (a) through (e) for a plurality of iterations, thereby storing a plurality of feedback values and a plurality of control settings, wherein adjusting the control setting comprises alternating between adjusting the in-phase setting and adjusting the quadrature phase setting for each of the iterations by inverting one or more bits of a first set of binary bits associated with the in-phase setting, and inverting one or more bits of a second set of binary bits associated with the quadrature phase setting; and (g) determining which one of the plurality of stored feedback values is preferred.
