Detailed representation of irregular LDPC code ensembles and density evolution
Kazuhiko Kasai, T. Shibuya, K. Sakaniwa · 2003
We construct new families of low-density parity-check (LDPC) code ensembles which are subensembles of conventional irregular LDPC code ensembles and develop density evolution for those ensembles. Further, we find an ensemble which has a better threshold than that of its super ensemble.
