Zusammenfassung:An apparatus and method for active noise cancellation, including but not limited to, noise cancellation at VLF frequencies. The invention facilitates the reception of critical information in variable and extreme EMI scenario with no information about the signal of interest. The invention utilizes an automated, signal agnostic active noise cancellation technique and associated hardware components. In order to extract the signal of interest, vector modulation is employed to the signal from the noise only antenna so as to match it and then subtract it from the received signal containing combined noise and signal of interest. This apparatus and method ensures that a signal of interest can be extracted from an extremely noisy environment without any knowledge about the characteristics of that signal.
