Abstract:
A system for integrated self-interference cancellation, comprising a transmit coupler, coupled to a transmit signal, that samples the transmit signal to create a sampled transmit signal; an analog self-interference canceller, coupled to the transmit coupler, comprising a controller; a signal divider, that splits the sampled transmit signal into a set of signal components; a set of phase shifters, wherein a phase shifter of the set shifts a signal component of the set of signal components by a total phase shift value; a set of scalers, wherein a scaler of the set scales the signal component by a total scale factor; a signal combiner, that combines the set of signal components into a self-interference cancellation signal; and a receive coupler, coupled to a receive signal, that combines the self-interference cancellation signal with the receive signal to remove a portion of self-interference present in the receive signal.
