LDPC Codes

LOPT - Online Optimisation of LDPC and RA degree distributions

Look for an optimised LDPC degree distribution. You enter the code rate and allowed degrees.

Please see An introduction to density evolution with LODE and LOPT for more information on how to use LOPT. To find the threshold of your own degree distribution use LODE Online Density Evolution
