FIELD: adaptive antennas for satellite communication systems. ^ SUBSTANCE: proposed method includes suppression of single noise when single compensation channel is available or more than single noise in case there is respective number of compensation channels with signals received over side lobes of main-antenna directivity pattern in satellite communication system. Signals received are numbered and expanded into quadrature components in analog-to-digital converters, this being followed by quadrature processing. Signal readout delay is introduced in compensator channels while weighting coefficient is being computed using adaptive algorithm in digital processor. The latter functions to compute optimal weighting coefficients using sample correlation matrix access. Time required for computing according to adaptive algorithm and for operations related to data input in digital processor and weighting coefficient output from digital processor is shorter than delay time introduced, that is, it meets on-line computation requirement. ^ EFFECT: ability of on-line noise suppression during zero-length transient process. ^ 1 cl, 9 dwg |
