More Information
Summary:Described herein is a device that includes at least one radio frequency transmitter; at least one radio frequency receiver; a copy block configurable to output a digital representation of a currently transmitted signal and a model having a representation of at least analog circuitry of the at least one radio frequency transmitter and analog circuitry of the at least one radio frequency receiver, as well as possibly one or more antennas. The model generates, in response to the digital representation of the currently transmitted signal, a self-interference compensation signal to compensate, in the digital domain, a signal that is received simultaneously with the currently transmitted signal. Also described are corresponding apparatus, methods, computer program instructions stored in a memory medium, and an integrated circuit embodiment.
