METHOD FOR NOISE-IMMUNE TRANSMISSION OF INFORMATION IN SHORT-WAVE COMMUNICATION SYSTEMS Russian patent published in 2025 - IPC G08C19/28 

FIELD: telecommunication systems.

SUBSTANCE: disclosed is a method for noise-immune transmission of information, in which the original bit sequence is subjected to a randomization operation, after which the bit stream is re-encoded into a substituting compressed noise-immune ternary code and, when received, the integrity of the stream is monitored, then the stream is transmitted over the radio channels of the parallel radio modem, phase demodulation is performed on the receiving side, performing error control based on comparisons of the control ternary symbol transmitted over the allocated radio channel and its restored copy, if they differ, the results of the current control of the energy of the received two controlled symbols are used, error is corrected in the radio channel in which the signal-to-noise ratio was the least, redundancy is eliminated, as a result, copies of a randomized sequence of a binary code are formed, de-randomization is carried out, as a result of which an initial code representation of the transmitted information is obtained.

EFFECT: high noise immunity without introducing structural redundancy and in detecting errors.
