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.
