Weight distributions of binary low-density parity-check (LDPC) codes are well studied in [1],[5],[4],[2]. We investigate the average distributions of symbol and binary weight for non-binary LDPC code ensemble. We derive the asymptotic growth rate ...

We consider communication over the binary erasure channel (BEC) using low-density parity-check (LDPC) code and belief propagation (BP) decoding. Furthermore, a gap between the bit error probability after finite number of iterations for finite bloc...

Luby et al. derived evolution of degree distributions in residual graphs for irregular LDPC code ensembles. Evolution of degree distributions in residual graphs is an important characteristic which is used for finite-length analysis of the expecte...

The average bit erasure probability of a binary linear code ensemble under maximum a-posteriori probability (MAP). decoding over binary erasure channel (BEC) can be calculated with the average support weight distribution of the ensemble via the EX...
Spatially coupled (SC) low-density parity-check (LDPC) codes are denned by bipartite graphs that are obtained by assembling prototype graphs. The combination and connection of prototype graphs are designated by specifying some parameters, and Kude...

conventional secret sharing, password protected secret sharing (PPSS) was invented. Recently, Nakahara et al. improved Ogata's multiple-use PPSS (mPPSS), which protects multiple data by one password, by employing secure computation known as CSEC70...

In this talk, a group theoretic representation suitable for the
rank-modulation (RM) scheme over the multi-cell ranking developed by
En Gad et al. is presented. By introducing an action of the group of
all permutation matrices on the set of all pe...
