METHOD AND DEVICE FOR SUPPRESSING CROSS-POLARISED NOISE Russian patent published in 2009 - IPC H04J11/00 

FIELD: physics.

SUBSTANCE: invention relates to the technology of suppressing noise between cross-polarised waves. The device for suppressing cross-polarised noise comprises: an error detector (26) for extracting the difference between the demodulated signal, which is a copolarisation signal, in which there cross-polarisation error is compensated, and the received signal, which indicates the ideal state of copolarisation, and output of the error signal, which indicates the extracted difference; a phase noise detector (27), for output of the phase noise difference by comparing the signal which compensates cross-polarised noise, which is a signal with opposite polarisation, in which cross-polarised noise is compensated, with the error signal; a control signal generator for generating a control signal, corresponding to the phase noise difference; and a phase changer (18), situated before and after cross-polarised noise suppressors, for generating a signal which compensates cross-polarised noise, for controlling the phase signal which compensates cross-polarised noise in such a direction that, phase noise difference is suppressed in response to input of a control signal.

EFFECT: eliminating effect of phase noise of a local generator on possibility of suppressing cross-polarised noise.
