Abstract: A low-density parity-check (LDPC) decoding method includes exchanging messages between check nodes and variable nodes based on scheduling information representing an order of exchanging messages between the check nodes and the variable nodes for an LDPC decoding, and performing the LDPC decoding based on the exchanged messages, wherein the scheduling information is determined by manipulating at least one of an order of the check nodes and an order of the variable nodes in an LDPC bipartite graph.
