METHOD OF TRANSMITTING MULTI-UNIT MESSAGES IN TELECODE COMMUNICATION SYSTEMS Russian patent published in 2020 - IPC H04L1/20 H03M13/29 

FIELD: data processing.

SUBSTANCE: invention relates to processing and transmission of information and is intended for noise-immune transmission of multi-unit messages. To achieve the technical result on the transmitting side, the message is divided into information units, each of which is encoded with the original noise-immune code, wherein symbols of a sequence of original noise-immune codes with identical numbers are first coded with a first-stage code of a multidimensional cascade code, then, said code symbols are encoded with a second-stage code and finally coded with a code of the last step of the multidimensional concatenated code, the number of which corresponds to the number of measurements of the multidimensional cascaded code. At the receiving side, cyclic synchronization is used to determine the beginning of the sequence of original noise-immune codes which are decoded with control of decoding accuracy and deletion of incorrectly decoded original noise-immune codes. Further, multiple attempts are made to decode multidimensional cascade code, after each of which restoration of message information units is checked, wherein each repeated decoding attempt is carried out while reducing the number of erased message information units, and if the previous number is stored, the decoding attempt is terminated and the entire message is erased. Message units are then assembled into one message, which is sent to message recipient.

EFFECT: higher noise immunity.
