Reducing receiver performance degradation due to frequency coexistence
Abstract:
Systems and apparatuses are provided for negating the degradation effects of fundamental coupling between at least two near field communication (NFC) enabled devices, at least one of which can receive frequency modulation (FM) signals. Due to the fundamental coupling, strong NFC signals can mix with blocking signals associated with a desired/tuned-to FM frequency causing degradation in FM receiver performance. By utilizing a notch filter at the front end of the FM receiver, the degradation in FM receiver performance caused by the fundamental coupling phenomenon can be avoided.
