The program searches for a girth 10 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-10 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 ten-cycles. The program may fail to find a code given particular parameters. It also does not find the smallest codes compared to other algorithms.

Version Published Release Notes
1.1.0.0

In the previous version only the sequential selection of rows was included in the program. Random selection is included and made default. Random selection may lead to better codes in terms of error correction.
