METHOD OF DETERMINING NOISE-PROOF CODE PARAMETERS Russian patent published in 2017 - IPC H03M13/11 

FIELD: radio engineering, communication.

SUBSTANCE: in the method, if the number of nonzero syndromes is less than the threshold value, code implementations are accumulated and the analyzed matrix of the required dimension is formed. In the future, the resulting matrix is converted to a lower triangular shape. At the same time, the matrix of the supposed check code equations is formed. In the resulting lower triangular matrix, the weight of the columns in the check area is determined. The column index, the weight of which does not exceed the threshold value, indicates the true verification equation in the matrix of the supposed check code equations. Using the found equations and the iterative confidence spread algorithm, the accumulated code implementations are decoded. Again, the analyzed matrix is formed and the sequence of operations described above is performed on it until all the check code equations are found.

EFFECT: improving the performance of the information receiving system.
