A method for the extraction of communication interference, may include converting a digital baseband signal into an analog signal, transmitting the analog signal; receiving the analog signal, converting the analog signal after receipt into a received digital signal, modulating the digital baseband signal to generate a reference signal, estimating a delay between the received digital signal and the reference signal, generating an aligned reference signal based on the reference signal and the delay, estimating a transmission gain of the received digital signal based on the received digital signal and the aligned reference signal, multiplying the aligned reference signal by the transmission gain to generate a scaled reference signal, and subtracting the scaled reference signal from the received digital signal to generate an estimated interference present in the received digital signal.
