SUPPRESSION OF NOISE IN CROSS POLARISATION IN ORTHOGONAL COMMUNICATION LINE Russian patent published in 2008 - IPC H04J11/00 H04B7/204 

Abstract RU 2339168 C2

FIELD: physics, communication.

SUBSTANCE: invention is related to suppression of noises in cross polarisation in communication systems, in which orthogonal channels are used, and more precisely, to communication systems with multiple access with orthogonal code separation of channels (MAOCSC), in which identical long code is used in channels of both polarisations, at the same time supporting suppression of noise in cross polarisation. Method contains coding of the first transfer signal with long code in the first remote terminal; conversion of the first transfer signal coded by long code into the first polarised transfer signal with application of the first polarisation format; coding of the second transfer signal with the long code in the second remote terminal, at that the first and second transfer signals are orthogonal to each other; conversion of the second transfer signal coded with long code into the second polarised transfer signal with application of the second polarisation format; and transfer of the first and second polarized transfer signals to at least one destination point.

EFFECT: improvement of signal ratio to interference and noise.
