Claim:
1. A method for self-interference canceller tuning comprising: generating a tuning calibration profile based on both component calibration data and system calibration data of an analog self-interference canceller; detecting a tuning trigger, wherein the tuning trigger is detected in response to either time since last tune exceeding a time threshold or temperature change over a time interval exceeding a temperature change threshold; calculating a set of tuning parameters in response to the tuning trigger; wherein the set of tuning parameters comprises complex weights for a set of taps of the analog self-interference canceller; wherein each tap of the set of taps is associated with a filter; and applying the set of tuning parameters based on the tuning calibration profile; wherein applying the set of tuning parameters comprises setting attenuator values for each tap of the set of taps.
