Abstract:
Full duplex transceivers are provided, the transceivers comprising: a transmitter section that includes an analog portion having analog baseband signals and a digital portion having digital baseband signals; a receiver section that includes an analog portion having analog baseband signals and a digital portion having digital baseband signals; an analog self-interference canceller that, in response to the analog baseband signals in the analog portion of the transmitter section, produces analog cancellation signals that cancel first self-interference in the analog baseband signals in the analog portion of the receiver section; and a digital self-interference canceller that, in response to the digital baseband signals in the digital portion of the transmitter section, produces digital cancellation signals that cancel second self-interference in the digital baseband signals in the digital portion of the receiver section.
