Abstract: The invention provides a CC-QC-LDPC code construction method and a decoding device. A memory comprises 4 groups 12, 13, 14, 15, which respectively store specified information, each iteration of a sub-decoder 11 comprises decoding states in the same number as the matrix rows J in a sub-code check matrix, each decoding state updates a layer, z check nodes of each layer are processed in G phases, each decoding state comprises G decoding phases, z/G check nodes carry out parallel processing in each decoding phase, and the z/G check nodes and associated variable nodes are updated. The CC-QC-LDPC code construction method provided by the invention has the beneficial effects that the length of the LDPC code is effectively and efficiently expanded, the decoding accuracy is greatly improved, the storage demand is reduced, the complexity and the error rate of the decoding device are relatively lower than that of other similar decoding devices, and the overall performance is excellent.
