MANNER OF CODE CYCLIC SYNCHRONIZATION Russian patent published in 2003 - IPC

FIELD: transmission of discrete information, cyclic synchronization employed in systems with noise- immune protection of information with use of correcting, specifically, concatenated codes. SUBSTANCE: salient feature of method lies in that symbols of numbering sequence are summed up with part of symbols of testing part of noise-immune code and the rest of symbols of testing part of noise-immune code are summed up with symbols of synchronizing sequence which is detected by way of multiplication of input sequence by testing polynomial of noise-immune code. Numbering sequences include check digits. Check digits are tested, only those numbering sequences for which check test is carried out are used in comparison of numbering sequences. EFFECT: increased noise immunity and decreased complexity of hardware and software realization. 1 dwg
