摘要：An encoder and a decoder employ an encoding scheme corresponding to aparity check matrix which is derivable from a bipartite protograph formed of variablenodes and check nodes, with each variable node corresponding to a codeword symbol

position. The protograph has a plurality of groups of nodes, each group of nodescomprising both variable nodes and check nodes. Each of the check nodes in a group is ofdegree 2 and has connections to two variable nodes in the same group. The protographalso has a plurality of check nodes of degree n, where n is the number of said plurality ofgroups, wherein each of the plurality of check nodes has a connection to a variable nodein each group such that the symbol positions in a codeword are interleaved between thegroups of nodes.
