Industrial Automatic Control Systems and Controllers Annotation << Back Weak Signals in Real Communication Channels Barsukov S.N., Malkov A.L., Morozova T.Yu., Andrushchenko A.G. In work it was investigated asymptotic effective of optimal criterion of defection of faint signal in scheme of series. The number of observations is increased , the hypothesis in drown together with speed This work about the quantity of the prize. This prize is a effective of detection of signal with non Gauss noise compare with detection of signal with Gauss noise. E-mail: bsn_mgapi@mail.ru, amalkov@bk.ru
