Abstract

Radio frequency (RF) communication systems with coexistence management are provided herein. In certain embodiments, a method of coexistence management in a mobile device includes providing an RF receive signal from a first front end system to a first transceiver, generating an RF transmit signal and an RF observation signal using a second front end system, the RF observation signal generated based on observing the RF transmit signal, generating digital observation data based on the RF observation signal using a second transceiver, downconverting the RF receive signal to generate a baseband receive signal using the first transceiver, and compensating the baseband receive signal for RF signal leakage based on the digital observation data using the first transceiver.
