Description

The program constructs girth-6 type III qc-ldpc codes given base matrix and sub-matrix size. The sub-matrices sizes are variable. The program uses a search algorithm. It could fail to construct a code given some parameters. In that case the user could try many times or could simply increase the size of the code to improve chances of finding a code. The constructed code is stored in H.
