The present invention relates to an anti-jamming technique, and more particularly, to a method and a system for anti-jamming based on empirical mode decomposition and wavelet de-noising schemes which effectively remove, by passing through two steps, a signal in which an interference and a jamming signal received in a receiver are mixed. According to the present invention, an empirical mode decomposition scheme is primarily applied, and a wavelet de-noising scheme based on an adaptive threshold value is secondarily applied, thereby obtaining a gain in a signal-to-noise ratio.
