Abstract
A full-duplex radio device is disclosed. The full-duplex radio device includes an analog transmission (TX) circuit that includes a power amplifier to output an analog TX signal. The full-duplex radio device also includes a feedback receiver circuit coupled to the analog TX circuit. The feedback receiver circuit provides a digital representation of the analog TX signal that is used to digitally cancel at least a transmitter noise component of a self-interference signal associated with a transmission of the analog TX signal in the full-duplex radio device.
Claims24
A full-duplex radio device configured to cancel a self-interference signal in a digital domain, the full-duplex radio device comprising:
- a transmitter comprising a power amplifier to output an analog TX signal;
- and
- a feedback receiver circuit, coupled to the transmitter, to provide a digital representation of the analog TX signal to digitally cancel at least a transmitter noise component of the self-interference signal associated with a transmission of the analog TX signal in the full-duplex radio device.
A full-duplex radio system comprising:
- a transmission (TX) circuit comprising a power amplifier to output an analog TX signal;
- and
- a feedback receiver circuit operatively coupled to the TX circuit to receive a feedback cancellation signal and the analog TX signal, the feedback receiver circuit to cancel a portion of the analog TX signal based on the feedback cancellation signal and to generate a digital representation of a remaining portion of the analog TX signal, wherein the digital representation of the remaining portion of the analog TX signal is to digitally cancel in a digital domain at least a transmitter noise component of a self-interference signal associated with a transmission of the analog TX signal in the full-duplex radio system.
A full-duplex radio device comprising:
- a means for providing an analog transmission (TX) signal for a transmission in the full-duplex radio device;
- and
- a means for digitally canceling at least a transmitter noise component of a self-interference signal associated with a transmission of the analog TX signal in the full-duplex radio device, wherein the canceling is based on a digital representation of the analog TX signal.
