FIELD: radio engineering, communication.
SUBSTANCE: signals coming from outputs of an N-element antenna system are digitised in N analogue-to-digital converters, processed in a digital computer, where a covariance matrix is generated and decomposed into eigen vectors and eigen values. Further, N signals free of J powerful non-correlated interferences, under the condition that N>J, are transmitted to inputs of the devices designed for extracting useful information.
EFFECT: removing the noise component from each receiving channel of the used device while preserving useful information in each channel.
