摘要： In one embodiment, the present patent application comprises a method and apparatus to generate low rate protographs from high rate protographs, comprising copying a base graph; permuting end points of edges of a same type in copies of the base graph to produce a permuted graph; and pruning systematic input nodes in the permuted graph and the edges connected to them. In another embodiment, the present patent application comprises a method and apparatus to generate high-rate codes from low-rate codes, comprising puncturing a subset of codeword bits, wherein the step of puncturing a subset of codeword bits comprises regular-irregular puncturing the subset of codeword bits, random puncturing variable nodes, or progressive node puncturing variable nodes to obtain a desired code from a preceding code.
摘要翻译：在一个实施例中，本专利申请包括从高速原始图生成低速原始图的方法和装置，包括复制基图; 将相同类型的边缘的端点置换为基图的副本以产生置换图; 并修改置换图中的系统输入节点和与其连接的边缘。在另一个实施例中，本专利申请包括从低速率码产生高速率码的方法和装置，包括对码字比特的子集进行删截，其中，对码字比特的子集进行删截的步骤包括规则不规则的穿孔子集码字比特，随机删截可变节点或逐行节点删截可变节点，以从前面的代码获得期望的代码。
