METHOD OF CODE CYCLIC SYNCHRONISATION Russian patent published in 2010 - IPC H04L7/08 

FIELD: machine building.

SUBSTANCE: proposed method consists in that accepted input sequence made up of several words coming one after another, each representing modulus digit-by-digit sum, of two noise-resistant cyclic codes, synchronising sequence and numbering sequence are multiplied by verification polynomial of noise-resistant cyclic code and by verification polynomial of numbering sequence to obtain the sum of syndrome of noise-resistant cyclic code and synchronising sequence. Then numbering sequence of accepted noise-resistant cyclic code is extracted and compared with numbering sequences of noise-resistant cyclic codes accepted earlier. The number of agreements of numbering sequences with those accepted earlier in one of F agreement counters. If numbering sequence agrees with numbering sequences accepted earlier, the number in appropriate agreement counter is increase by 1, and, if the number of agreements exceeds that written in appropriate counter of threshold value agreements, code cyclic synchronisation of input sequence is taken to result.

EFFECT: simplified procedure.
