INFORMATION PROCESSING METHOD AND COMMUNICATION DEVICE Russian patent published in 2021 - IPC H03M13/11 H04L1/00 

FIELD: information processing means.

SUBSTANCE: encoding an input bit sequence using an LDPC matrix with low density of parity checks, where the LDPC matrix is obtained based on the base graph, and base graph includes submatrices A, B, C, D and E, where submatrix A is a matrix including rows m_A and columns n_A, m_A and n_A are natural numbers, 4 ≤ m_A ≤ 7 and n_A = 10, submatrix B is a matrix including rows m_A and columns m_A, and submatrix B includes a column with weight 3 and submatrix B', having a bidiagonal structure, submatrix D includes rows m_D in matrix F, matrix F is a matrix including rows m_F and columns (m_A + n_A), m_D and m_F are natural numbers, 0 ≤ m D ≤ m_F and 35 ≤ m_F ≤ 38, submatrix C is a completely zero matrix including rows m_A and columns m_D, and submatrix E is a unit matrix including m_D rows and m_D columns.

EFFECT: technical result is higher efficiency of encoding information.
