More than 300 matrices are available for NB-LDPC codes defined on GF(64) and GF(256).
Matrix definition, topological properties and performance are given for each set of matrices.
To access to the data base, go to: http://www-labsticc.univ-ubs.fr/nb_ldpc/, click "matrices", and "New! matrices and simulation results from UBS".
