RADIO FREQUENCY COMMUNICATION SYSTEMS WITH COEXISTENCE MANAGEMENT

Abstract:

Radio frequency (RF) communication systems with coexistence management are provided herein. In certain embodiments, a mobile device includes a first antenna, a first front end system that receives an RF receive signal from the first antenna, a first transceiver coupled to the first front end system, a second antenna, a second front end system that provides an RF transmit signal to the second antenna, and a second transceiver coupled to the second front end system. The first front end system generates a first observation signal by observing the RF receive signal, and the second front end system generates a second observation signal by observing the RF transmit signal. The first transceiver also downconverts the RF receive signal to baseband, and uses the first observation signal and the second observation signal to compensate the baseband receive signal for RF signal leakage.
