中文说明：这个压缩文件包含了MATLAB的源代码，用于生成不同标准的H矩阵，如WIFI、WIMAX、CCSDS、DVB-S2等。由于QC-LDPC码由于其较低的完整性和较好的译码性能在这些标准中得到了广泛的应用，因此本文利用matlab编程实现了这些标准的H矩阵的生成。希望它能对有需要的人有所帮助。
English Description：
this compressed file contains the source code of MATLAB for genarating H matrix of different standands, such as WIFI, WIMAX, CCSDS,DVB-S2,and so on. since the QC-LDPC codes are wildly used in these standands for its low-compleity and promissing decoding performance, so i design the source code by using matlab to genarate H matrix of these standands. hoplt it helpful for people who need this.
