Multi-edge type LDPC codes are introduced by Richardson and Urbanke, and they show examples of their ensembles have better performance than other known ensembles. Orlitsky et al. derived the condition for irregular LDPC code ensembles with small l...

In this paper, we consider communication over the binary erasure channel (BEC) using low-density parity-check (LDPC) codes. We consider MAP decoding not using a whole Wanner graph but only a neighborhood graph of fixed depth preferred to as local-...
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...
