摘要： This application discloses an encoding method, an apparatus, a communication device, and a communication system. The method includes: encoding an input bit sequence by using a low density parity check LDPC matrix, where the LDPC matrix is obtained based on a base graph, and the base graph includes submatrices A, B, C, D, and E, where the submatrix A is a matrix including m A rows and n A columns, m A and n A are positive integers, 4≤ m A ≤ 7, and n A =10; the submatrix B is a matrix including m A rows and m A columns, and the submatrix B includes a column whose weight is 3 and a submatrix B' having a double diagonal structure; the submatrix D includes m D rows in a matrix F, the matrix F is a matrix including m F rows and ( m A + n A ) columns, m D and m F are positive integers, 0≤ m D ≤ m F , and 35 ≤ m F ≤ 38; the submatrix C is an all zero matrix including m A rows and m D columns; and the submatrix E is an identity matrix including m D rows and m D columns. The encoding method, the apparatus, the communication device, and the communication system in this application can support a requirement for encoding information bit sequences of various lengths.

摘要： This application discloses an encoding method, an apparatus, a communications device, and a communications system. The method includes: encoding an input bit sequence by using a low density parity check (LDPC) matrix, where the LDPC matrix is obtained based on a lifting factor Z and a base matrix, and the base matrix includes row 0 to row 6 and column 0 to column 16 in one of matrices shown in FIG. 3b-1 to FIG. 3b-8 , or the base matrix includes row 0 to row 6 and some columns of column 0 to column 16 in any matrix shown in FIG. 3b-1 to FIG. 3b-8 . The encoding method, the apparatus, the communications device, and the communications system in this application can support an encoding requirement for information bit sequences with a plurality of lengths.
