Abstract: A system and method for non-linear digital self-interference cancellation including a pre-processor that generates a first pre-processed digital transmit signal from a digital transmit signal of a full-duplex radio, a non-linear transformer that transforms the first pre-processed digital transmit signal into a non-linear self-interference signal according to a transform configuration, a transform adaptor that sets the transform configuration of the non-linear transformer, and a post-processor that combines the non-linear self-interference signal with a digital receive signal of the full-duplex radio.

Abstract: A method for pilot signal based self-interference cancellation tuning includes detecting a tuning trigger and in response to the tuning trigger, generating a pilot transmit signal according to the trigger data; and transmitting, at the transmitter, the pilot transmit signal; receiving, at the receiver, a pilot receive signal; cancelling, at the self-interference canceller, a portion of self-interference in the receive pilot signal, resulting in a composite pilot signal; analyzing the composite pilot signal; and tuning a configuration parameter of the self-interference canceller, based on analysis of the composite pilot signal, resulting in reduced self-interference in the composite pilot signal.
