SYSTEM FOR TRANSMITTING QUADRUPLE-ENCODED RADIO SIGNALS Russian patent published in 2005 - IPC

FIELD: radio communications.

SUBSTANCE: system has transmitting portion, which contains clock pulse generator 1, first and second D-code generators 2₁-2₂, first and second generator of double frequency manipulation 3₁-3₂, adder 4, modulator 5, frequencies synthesizer 6, pseudo-random numbers generator 7. said portion is connected through broadcast line 8 to receiving portion, which has demodulator 9, frequencies synthesizer 10, pseudo-random numbers 11, signals selector 12, clock pulses generator 13, block for selecting additional series 14, block for folding additional series 15, solving block 16. new set of significant features provides for possible implementation of distributed receipt with code structure of specific orthogonal quadruple-encoded series without expansion of available frequency resource.

EFFECT: broader functional capabilities, higher trustworthiness, higher efficiency, higher interference resistance.
