FIELD: information processing.
SUBSTANCE: invention relates to the field of processing and transmission of discrete information. To realise the described effect, a method for transmitting multiblock messages by cascade code is proposed, consisting in the fact that the source information on the transmitting side is divided into blocks of a predetermined length, used to form a message. A message is comprised of a title used to determine the sequence number of the blocks, an information or verification block, and a verification stage. Sets of verification blocks are then formed for sets of these blocks. A synchronising sequence is added to each block encoded by a cascade code, and the obtained combination of characters is transmitted to the receiving side. Synchronisation is performed not only by error-free code words, but also by code words containing errors. Decoding is performed simultaneously for hard and soft solutions, and multiple attempts are made in decoding the matrices of the multiblock message. Low-level matrices are used in encoding. After the blocks are decoded, the original messages are collected and transmitted to the recipient.
EFFECT: increasing the reliability of transmission of multiblock messages and reducing the time of transmission thereof.
