Abstract(in English) | Decoding performance of LDPC(Low-Density Parity-Check) codes over a binary erasure channel(BEC) is highly dependent on the degree distributions of the Tanner graphs. We compare two types of LDPC code ensembles having uniform degree distributions and non-uniform ones respectively. Then we provide a sufficient condition for the erasure probability of a BEC for which the decoding performance for the ensembles with uniform degree distributions is superior to that with non-uniform ones. |
