METHOD OF AND DEVICE FOR ADAPTIVE COMPENSATION FOR CROSS-POLARIZED NOISE Russian patent published in 1995 - IPC

Abstract RU 2048682 C1

FIELD: radio receiving systems of satellite communication lines with reuse of frequencies due to polarized multiplexing of signals. SUBSTANCE: device implementing method has antenna of radio receiving system 1, two 180-deg. variable phase inverters 2,4, differential phase shifter 3, polarization selector 5, two low-noise amplifiers 6,7, six power splitters 8-13, three attenuators 14-16, two phase shifters 17,18 for two fixed positions, two adders 19,20 four switches 21-24, two cross-polarized coupling meters 24,25, threshold comparison unit 27, β, Ψ, w1, w2 computing unit 28, device control unit 29, two phase inverter control units 30, 32, differential phase shifter control unit 31. EFFECT: elimination of uncertainty in placing compensating elements in position affording minimum of cross-polarized noise. 2 cl, 5 dwg
