LDPC decoder for Chinese DTV standard. This code works for all code rate,only need to change is Paritycheck matrix.I have tried with 1/2 code rate.

this is code for "embeded extended visual cryptography ". I had done programming in MATLAB. >>steps to run the program: Type add only in command window. I had run this code on Matlab 7.1

ieee各种节点图形，仅供参考。电力系统的分析和计算中，需要不同网络结构和参数。在应 用这些参数之前，收集和整理工作会花费大量的时间和精力。(ieee various node graph, for reference only. Power system analysis and calculation, require different network structures and parameters. Before applying these parameters, the collection and collation will spend a lot of time and effort.)
