Abstract
A wireless communication device can include a transmitter subsystem configured to transmit a transmit signal that, once propagated from the wireless communication device, may be reflected back and received by a receiver subsystem as interference. The wireless communication device can include a self-interference cancellation subsystem configured to generate a cancellation signal to mix with received signals to mitigate self-interference effects. A performance floor for the self-interference cancellation subsystem may be determined based on a phase noise profile of an oscillator of either or both the transmitter subsystem or the receiver subsystem. The performance floor metric can be thereafter used to inform an operation or operational setting of the wireless communication device.
