Industrial Automatic Control Systems and Controllers Annotation << Back A Two-stage Algorithm for Adaptive Spatial Processing of Signals in Communication Lines HF A.V. Nikolaev The article describes an approach to improving the quality of communications links decameter waves through the use of two-stage adaptive algorithm for spatial signal processing in antenna arrays. The fi rst stage involves the estimation of spatial parameters of the interference. The second phase calculates the weight vector for forming a desired beam of the antenna array. This allows to dynamically shape the radiation pattern of the antenna array in complex, changing conditions signal-jamming environment. Keywords: short-wave radio communications; adaptive antennas array; signals adaptive spatial processing; the weight vector. Contacts: E-mail: Alex.Nik@rambler.ru Pp. 39-46.
