摘要从线性码的生成矩阵出发，研究线性码的自同构群。 - In chapter 3 , we propose the methods for finding the generator matrix of a quasi - cyclic ldpc in “ systematic form ” from its parity - check matrix and its corresponding encoding schemes
在第三章,我们继续介绍了准循环结构的ldpc码生成矩阵的求解及其对应的编码方案。 - These quasi - cyclic ldpc can not only reduce the storage of ldpc generator matrix , but also decrease the encoding complexity efficiently , which is of great significance for the applications . furthermore , simulations show that well - designed quasi - cyclic ldpc can perform as well as those random - generated ldpc codes . and in the last section of chapter3 , we present a “ quasi - cyclic ldpc based ” code division scheme , which can be possibly applied to the adaptive coding
这些特殊结构的ldpc码不仅可以压缩编译码所需的矩阵储存空间,而且还能有效的降低编码复杂度,这对工程上实现ldpc码的应用具有重要的意义;而且通过仿真,我们还可以证明,合理设计的准循环ldpc码的性能可以达到随机构造的ldpc码的性能。 - This thesis offers a comprehensive study on the performance of ldpc codes . the author first presents a new method for construction of irregular ldpc codes based on generator matrix in order to significantly reduce encoding complexity . the simulation results are obtained over an awgn channel , and the obtained results are also compared with those acquired by the traditional approaches
本文在对ldpc码进行了系统的分析和研究的基础上,为了降低编码复杂度,我们首次提出了一种基于生成矩阵的非正规ldpc码的构造方法,并将其性能和传统的基于校验矩阵的ldpc码进行了比较。 - Ldpc code belongs to the linear block code which is encoded by the information sequence multiplies generator matrix . although the parity - check matrix of ldpc code is sparse , the generator matrix is not . the encoding complexity of it is linearly proportional to the square of code length
Ldpc码属于线性分组码,线性分组码的通用编码方法是由信息序列根据码的生成矩阵来求相应的码字序列,尽管ldpc码的校验矩阵是非常稀疏的,但它的生成矩阵却并不稀疏,这使得其编码复杂度往往与其码长的平方成正比。
