Zusammenfassung:	Disclosed systems and methods relate to an adaptive harmonic cancellation circuit for communication. The adaptive harmonic cancellation circuit includes a harmonic generator circuit configured to generate a reference harmonic of an interference signal. The adaptive harmonic cancellation circuit includes a harmonic prediction circuit coupled to the harmonic generator circuit. The harmonic prediction circuit is configured to receive an input signal including a target signal at a frequency and a radiated harmonic of the interference signal. The harmonic prediction circuit is configured to generate a predicted harmonic of the interference signal by modifying the reference harmonic of the interference signal to match the radiated harmonic of the interference signal in the input signal. The adaptive harmonic cancellation circuit includes a cancellation circuit coupled to the harmonic prediction circuit. The cancellation circuit is configured to obtain the target signal at the frequency by subtracting the predicted harmonic from the input signal.
