本文基于MATLAB/SIMULINK动态仿真环境，以实例阐述了建立脉冲编码调制通信系统仿真模型的一般方法。根据该系统的基本原理将整个模型划分为抽样﹑量化﹑编码等几个子系统，并在传输线路上加入高斯白噪声以检验该系统的传输质量和抗干扰能力。(Title Design and Simulation for PCM communication system Abstract )

QC-LDPC码生成矩阵编程，围长为12，无4环(The program searches for a girth 12 QC-LDPC code given size of sub-matrix, row and column weights. The configuration of sub-matrices could also be changed. The program offers flexibility in constructing girth-12 QC-LDPC codes compared to other algorithms. The program builds a Tanner graph by connecting groups of rows and columns. A connection is made if it does not form less than twelve-cycles. The program may fail to find a code given particular parameters. It also does not find the smallest codes compared to other algorithms. )
