Abstract: A system for self-interference canceller tuning includes a transmit coupler that creates a sampled analog transmit signal; an analog self-interference canceller that transforms the sampled analog transmit signal to an analog self-interference cancellation signal according to a set of tuning parameters, the set of tuning parameters comprising complex weights for a set of taps of the analog self-interference canceller; a tuning circuit that calculates the set of tuning parameters, and applies the set of tuning parameters to the analog self-interference canceller based on component calibration data of the analog self-interference canceller; and a receive coupler that combines the analog self-interference cancellation signal with the analog receive signal to reduce self-interference in the analog receive signal.

Abstract: A method for adaptively-tuned digital self-interference cancellation includes generating a digital self-interference cancellation signal from a digital transmit signal based on a transform configuration; combining the digital self-interference cancellation signal with a receive signal to form a digital residue signal; generating a composite residue signal from the digital residue signal and the digital transmit signal; and updating the transform configuration based on the composite residue signal.
