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.
