FIELD: information technology.
SUBSTANCE: invention relates to the processing and transmission of discrete information and can be used for noise-resistant information protection in the transmission of multi-block messages in communication complexes. Method consists in that, first, a message of a certain length is selected on the transmitting side. This message is then divided into blocks. For each specific set of blocks form, using a one-bit modulo two summation, its test block. For a set of check blocks, additional check blocks are then formed to increase the likelihood of their correct reception. Received message is again broken into new blocks. In the coded cascade code block intended for transmission to the channel, a synchronization sequence is added and the resulting combination of symbols is transmitted to the receiving side. At the receiving side, each block is decoded, and the received blocks are analyzed. Initial information of the undecodable blocks is restored with the help of a set of correctly pleasant blocks with the initial information and their verification blocks. After decoding and recovery, blocks with the original information are collected in a message and transmitted to the recipient.
EFFECT: technical result is to increase the reliability of transmission of multi-block messages and reduce the time of their transfer, as well as the possibility of using a previously developed fleet of equipment.
