Abstract: Systems and methods for signal path isolation for neutral-host hardware are provided. In one embodiment, an isolation circuit for a multiple-subchannel wireless communication transceiver comprises: a Tx path coupled to a transmit path output of a multiple-subchannel transceiver; a Rx path coupled to a receive path input of the transceiver; a precancellation circuit comprising: an isolation adjustment circuit within the transmit path of the isolation circuit, the isolation adjustment circuit comprising a phase shifter and a reflection tuner; a directional coupler within the Rx path of the isolation circuit. The isolation adjustment circuit outputs a reflected wave signal comprising a cancellation reference signal to the directional coupler. The cancellation reference signal comprises a complex conjugate of a TX signal leakage signal component of a signal transported in the Rx path of the isolation circuit. Within the directional coupler the cancellation reference signal destructively interferes with TX signal leakage signal component.

Abstract: In one example, a communications device includes transmit and receive signal paths, a duplexer coupled to the transmit and receive signal paths, and a feedback signal path coupled to the transmit signal path, wherein a portion of a transmit signal is decoupled into the feedback signal path as a feedback signal. The communications device further includes ADCs to convert feedback and receive signals to a digital feedback and receive signals. The communications device further includes a digital interference cancellation circuit to receive the digital feedback and receive signals, the digital interference cancellation circuit configured to: modify amplitude and phase of the digital feedback signal to generate a modified feedback signal; compensate the modified feedback signal for an impulse response of a coupling channel to generate a compensated, modified feedback signal; and combine the compensated, modified feedback signal with the digital receive signal to cancel, reduce, attenuate, or eliminate inference.
