| 摘 要： | 该文研究了原模图LDPC短码的设计及构造方法,输入码块的码率为1/2,码长为128比特和256比特的短码。在原模图设计的过程中,采用单位矩阵列随机交换生成的矩阵进行置换。同时基于最小距离和停止集的最大化原则,该文采用ACE算法进行处理,码元的变量节点的度取在3和5之间,因为增加变量节点的度能得到更大的最小距离,但是会增... |

| Abstract: | In this paper,research focuses on the design and structure of protograph-based LDPC codes with short block sizes.Mainly consider rate 1/2 codes with input block sizes 128 and 256 bits.As to the design of protograph,we use matrix produced by unit matrix interchanging randomly to permute code,which based on principle of maximizing the minimum distance and stopping set size.The paper adopts ACE algorithm.In particular as increasing the node degree leads to larger minimum distances,we consider codes with variab... |
