摘要： An encoder and a decoder employ an encoding scheme corresponding to a parity check matrix which is derivable from a bipartite protograph formed of variable nodes 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 nodes comprising both variable nodes and check nodes. Each of the check nodes in a group is of degree 2 and has connections to two variable nodes in the same group. The protograph also has a plurality of check nodes of degree n, where n is the number of said plurality of groups, wherein each of the plurality of check nodes has a connection to a variable node in each group such that the symbol positions in a codeword are interleaved between the groups of nodes.

摘要翻译： 编码器和解码器采用对应于奇偶校验矩阵的编码方案，其可从由可变节点和校验节点形成的二分原型图导出，每个可变节点对应于码字符号位置。 原型图具有多组节点，每组节点包括可变节点和校验节点。 组中的每个校验节点都是2级，并且具有到同一组中的两个变量节点的连接。 原型图还具有多个n度的校验节点，其中n是所述多个组的数量，其中多个校验节点中的每一个都具有到每个组中的可变节点的连接，使得码字中的符号位置 在节点组之间进行交织。
