FIELD: radio engineering.
SUBSTANCE: invention relates to radio engineering, in particular to methods of digital processing of radio signals. Disclosed is a method for space-time processing of radio signals for compensation of interference, which consists in the fact that signals coming from the outputs of the N-element antenna system are digitized in N analogue-to-digital converters, processed in a digital computer, where covariance matrix is calculated, decomposed for subsequent filtration, further, the signal, which is free from uncorrelated interference, is transmitted to the inputs of devices intended for extracting useful information, characterized by that in the process of calculating the covariance matrix, delay lines are used to store the products of complex digital signals at the last cycles of calculating the covariance matrix, based on the calculated products, the missing elements of the covariance matrix are restored, wherein an inverse matrix is calculated based on the covariance matrix, the calculation results of which are used in space-time signal processing.
EFFECT: high efficiency of space-time processing of radio signals by reducing computer hardware while maintaining accuracy of calculations.
