LDPC Codes

LOPT - Online Optimisation of LDPC degree distributions


Look for an optimised LDPC degree distribution. You enter the code rate and allowed degrees.
Alternatively you may wish to look at LODE Online Density Evolution
Please see An introduction to density evolution with LODE and LOPT for more information on how to use LOPT.
