Abstract
An encoding method, encoding device, decoding method and decoding device for low density generator matrix codes (LDGC) are disclosed. Wherein, the encoding method comprises: construct an LDGC mother code set using P LDGC with code rate Rand different code lengths, wherein the LDGC mother code set has a uniform basic matrix Gwherein, kdenotes the number of rows and ndenotes the number of columns in the basic matrix; obtain length L of an intermediate variant according to length K of an information bit sequence to be encoded in the LDGC mother code set; modify and expand the basic matrix to obtain a generator matrix Gusing the length L of the intermediate variant and the number kof rows in the basic matrix; and encode the information bit sequence to be encoded using a matrix G(1:L,1:N+L−K) composed of L rows and the front N+L−K columns of the generator matrix, wherein N denotes the length of the encoded information.
