Abstract
Radio frequency (RF) communication systems with coexistence management are provided herein. In certain embodiments, a method of coexistence management includes generating an RF observation signal based on observing a cellular transmit signal using a cellular front end system, processing the RF observation signal to generate digital observation data using a cellular transceiver, generating a digital wireless local area network receive signal based on processing an RF wireless local area network receive signal using a wireless local area network transceiver, processing the digital observation data to determine an estimated amount of aggressor spectral regrowth present in the RF wireless local area network receive signal using a spectral regrowth modeling circuit of the wireless local area network transceiver, and compensating the digital baseband wireless local area network receive signal for RF signal leakage based on the estimated amount of aggressor spectral regrowth.
