  • Signal extraction
    Patent number: 8351554
    Abstract: The invention relates to an adaptive method of extracting at least of desired electro magnetic wave signals, sound wave signals (40, 42), and any other signals from a mixture of signals (40, 42, 44, 46) and suppressing noise and interfering signals to produce enhanced signals (50) corresponding to desired (10) signals, and an apparatus (70) therefore. It relies on the concept of at least one of an attenuation of input signals in each sub-band for signals in such a manner that all desired (10) signals are attenuated less than noise or interfering source signals, and/or an amplification of input signals in each sub-band for source signals in such a manner that all desired (10) signals are amplified, and that they are amplified more than the noise and interfering signals.
