DEVICE OF TRANSFER, DEVICE OF RECEPTION AND METHOD OF TRANSFER IN OFDM MODE Russian patent published in 2013 - IPC H04J11/00

Abstract RU 2479132 C2

FIELD: radio engineering, communications.

SUBSTANCE: location of a signal of an SP-signal sent from the first transmitting antenna is arranged as identical to a location of an SP-signal sent from the second transmitting antenna. The SP-signal sent from the second transmitting antenna has polarity that is alternately repeating, inverted and non-inverted in one symbol relative to the SP-signal sent from the first transmitting antenna. Besides, the SP-signal sent from the second transmitting antenna is generated based on the condition that in the direction, in which the symbol number is increased by 1 and the carrier number is increased by 3, the polarity is fully inverted or non-inverted relative to the SP-signal, sent from the first transmitting antenna.

EFFECT: increased noise immunity in systems with multi-beam distribution.
