利用向量行分组的结构化LDPC设计
摘要：
利用向量行分组的结构化LDPC设计。建议了一种结构化的奇偶校验矩阵H，其中H是基础矩阵Hb的扩展。基础矩阵Hb包括区段Hb1和区段Hb2。区段Hb2包含具有权重wh＞＝3的列hb和具有双对角结构的H′b2，对于H′b2中在行i、列j的矩阵元素，当i＝j时，该矩阵元素等于1，当i＝j+1时，该矩阵元素等于1，在其他情况下，该矩阵元素等于0。布置hb和Hb1中的1，使得可形成mb/q个组，在每个组中的Hb的q个行不交叉。进一步，可以对基础矩阵Hb的行做置换，使得每两个相继的行不交叉。
摘要（英）：

A structured parity-check matrix H is proposed, wherein H is an expansion of a base matrix Hb. Base matrix Hb comprises a section Hb1 and a section Hb2. Section Hb2 comprises column hb having weight wh>=3 and H'b2 having a dual-diagonal structure with matrix elements at row i, column j equal to 1 for i=j, 1 for i=j+1, and 0 elsewhere. The 1's of hb and Hb1 are arranged such that one or more groups of the rows of Hb can be formed so that the rows of Hb within each group do not intersect. Further more, the rows of base matrix Hb can be permuted such that every two consecutive rows do not intersect.
