METHOD FOR INFORMATION TRANSMISSION USING SUBSTITUTE LOGICAL IMMUNITY CODE Russian patent published in 2021 - IPC G08C19/28 

FIELD: computing.

SUBSTANCE: invention relates to computing. The effect is achieved by performing (i) distributed structural and algorithmic transformations, at the final (i+1) stage of which the generated data stream, represented by a binary code, is converted into direct and inverse ternary codes with symbols that are represented in the form of pulse-width modulation (PWM₃), wherein each of the received PWM₃ substreams is summed with a meander pulse sequence, with a period T₀ equal to the duration of the original binary symbols, and taking values "+1" and "-1", as a result of which a bipolar pulse sequence is obtained in each of the substreams, which is then divided into even and odd symbols with the formation of semi-streams in each of the substreams; upon reception, the transition from the extended in phase modulation symbols of the in-phase and quadrature components to the accelerated initial representation is obtained using a gate "inhibit", to the inhibiting input of which a square wave signal is supplied; the half-streams in each of the substreams are combined, the generated original substreams are summed with the inverted meander, as a result of which the PWM₃ pulses of the original direct and inverse ternary codes are restored, after which, based on the obtained redundancy, transmission errors are detected and corrected at the symbol level of ternary codes.

EFFECT: invention increases the noise immunity of data transmission.
