Abstract

RF communication systems with interference cancellation for coexistence are provided herein. In certain embodiments, an RF communication system includes a transmitter that transmits a transmit signal through a first front end circuit, a receiver that processes a receive signal from a second front end circuit, and a feedback receiver that processes a feedback signal from the first front end circuit to generate a digital interference cancellation signal that compensates the receiver for interference arising from the transmitter.
