摘要：本公开的发明名称是“准循环LDPC码的移位值的设计”。根据一些实施例，一种供无线通信网络的无线传送器中使用的方法包括使用奇偶校验矩阵PCM来编码信息位，以及向无线接收器传送所编码的信息位。根据两个或更多个近似循环外消息度ACE约束来优化所述奇偶校验矩阵PCM。在一些实施例中，根据第一ACE约束来优化PCM的第一部分，并且根据第二ACE约束来优化PCM的第二部分。

主权项：1.一种无线装置110，可操作以：使用低密度奇偶校验LDPC码的奇偶校验矩阵PCM来编码信息位，所述PCM使用移位大小Z＝3*2j而被分割成大小为Z×Z的正方形子矩阵并通过大小为46x68的基矩阵被指定，其中j是0、1、2、3、4、5、6和7中的一个；以及向网络节点120传送与所编码的信息位对应的无线信号，其中所述基矩阵针对每个Z×Z子矩阵具有一个条目，所述条目为0对应于所述子矩阵是空矩阵，并且所述条目为1对应于所述子矩阵是循环置换矩阵，所述循环置换矩阵是通过将列向右循环移位k个元素而从Z×Z单位矩阵获得的，其中对于所述基矩阵的列c和行r中的非零条目，所述数量k通过modVe,Z被给出，其中Ve通过三元组r,c,Ve被指定，所述三元组由以下项给出：1,1,307,1,2,19,1,3,50,1,4,369,1,6,181,1,7,216,1,10,317,1,11,288,1,12,109,1,13,17,1,14,357,1,16,215,1,17,106,1,19,242,1,20,180,1,21,330,1,22,346,1,23,1,1,24,0,2,1,76,2,3,76,2,4,73,2,5,288,2,6,144,2,8,331,2,9,331,2,10,178,2,12,295,2,13,342,2,15,217,2,16,99,2,17,354,2,18,114,2,20,331,2,22,112,2,23,0,2,24,0,2,25,0,3,1,205,3,2,250,3,3,328,3,5,332,3,6,256,3,7,161,3,8,267,3,9,160,3,10,63,3,11,129,3,14,200,3,15,88,3,16,53,3,18,131,3,19,240,3,20,205,3,21,13,3,25,0,3,26,0,4,1,276,4,2,87,4,4,0,4,5,275,4,7,199,4,8,153,4,9,56,4,11,132,4,12,305,4,13,231,4,14,341,4,15,212,4,17,304,4,18,300,4,19,271,4,21,39,4,22,357,4,23,1,4,26,0,5,1,332,5,2,181,5,27,0,6,1,195,6,2,14,6,4,115,6,13,166,6,17,241,6,22,51,6,23,157,6,28,0,7,1,278,7,7,257,7,11,1,7,12,351,7,14,92,7,18,253,7,19,18,7,21,225,7,29,0,8,1,9,8,2,62,8,5,316,8,8,333,8,9,290,8,15,114,8,30,0,9,1,307,9,2,179,9,4,165,9,13,18,9,17,39,9,20,224,9,22,368,9,23,67,9,25,170,9,31,0,10,1,366,10,2,232,10,11,321,10,12,133,10,14,57,10,18,303,10,19,63,10,21,82,10,32,0,11,2,101,11,3,339,11,5,274,11,8,111,11,9,383,11,15,354,11,33,0,12,1,48,12,2,102,12,13,8,12,17,47,12,22,188,12,23,334,12,24,115,12,34,0,13,1,77,13,2,186,13,11,174,13,12,232,13,14,50,13,19,74,13,35,0,14,1,313,14,4,177,14,8,266,14,21,115,14,24,370,14,36,0,15,1,142,15,13,248,15,16,137,15,17,89,15,18,347,15,22,12,15,37,0,16,1,241,16,2,2,16,11,210,16,14,318,16,19,55,16,26,269,16,38,0,17,2,13,17,4,338,17,12,57,17,21,289,17,23,57,17,39,0,18,1,260,18,15,303,18,17,81,18,18,358,18,22,375,18,40,0,19,2,130,19,13,163,19,14,280,19,19,132,19,20,4,19,41,0,20,1,145,20,2,213,20,8,344,20,9,242,20,11,197,20,42,0,21,1,187,21,4,206,21,10,264,21,12,341,21,23,59,21,43,0,22,2,205,22,6,102,22,17,328,22,21,213,22,22,97,22,44,0,23,1,30,23,13,11,23,14,233,23,18,22,23,45,0,24,2,24,24,3,89,24,11,61,24,19,27,24,46,0,25,1,298,25,4,158,25,5,235,25,12,339,25,23,234,25,47,0,26,2,72,26,7,17,26,8,383,26,15,312,26,48,0,27,1,71,27,3,81,27,5,76,27,16,136,27,49,0,28,2,194,28,7,194,28,9,101,28,50,0,29,1,222,29,5,19,29,20,244,29,22,274,29,51,0,30,2,252,30,15,5,30,19,147,30,26,78,30,52,0,31,1,159,31,11,229,31,14,260,31,25,90,31,53,0,32,2,100,32,8,215,32,23,258,32,26,256,32,54,0,33,1,102,33,13,201,33,15,175,33,25,287,33,55,0,34,2,323,34,3,8,34,12,361,34,22,105,34,56,0,35,1,230,35,8,148,35,16,202,35,18,312,35,57,0,36,2,320,36,7,335,36,13,2,36,23,266,36,58,0,37,1,210,37,15,313,37,16,297,37,19,21,37,59,0,38,2,269,38,14,82,38,24,115,38,60,0,39,1,185,39,10,177,39,11,289,39,13,214,39,61,0,40,2,258,40,4,93,40,8,346,40,20,297,40,62,0,41,1,175,41,9,37,41,18,312,41,63,0,42,2,52,42,4,314,42,10,139,42,19,288,42,64,0,43,1,113,43,5,14,43,25,218,43,65,0,44,2,113,44,17,132,44,19,114,44,26,168,44,66,0,45,1,80,45,8,78,45,10,163,45,23,274,45,67,0,46,2,135,46,7,149,46,11,15,46,68,0。
