METHOD OF DIAGNOSING CYCLIC CODES Russian patent published in 2017 - IPC H04L17/00 

FIELD: radio engineering, communication.

SUBSTANCE: method of diagnosing cyclic codes involves selecting a certain number of code blocks and analysing different pairs of the code blocks. By means of a cyclically repeated procedure for shifting one of the polynomials describing the code blocks and bitwise addition modulo 2 of the polynomial pair to be processed, it is possible to find the common polynomial of the pair under consideration. The results of each analysis procedure are recorded, and after a sufficient number of procedures is performed, the number of results obtained for each detected type of common polynomials is compared. The desired generating polynomial is common to all code blocks and appears for the largest number of times. This is detected and used as a result of diagnosis.

EFFECT: increasing the noise immunity of information transfer.
