IEICE TRANSACTIONS ON FUNDAMENTALS OF ELECTRONICS COMMUNICATIONS AND COMPUTER SCIENCES E87A(10) 2484-2492 2004年10月 [査読有り]
In this paper, we provide explicit representations of average weight and stopping set distributions and asymptotic expressions of their exponent for detailedly represented irregular LDPC code ensembles. Further we present numerical examples which ...

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...
2018 The International Symposium on Information Theory and Its Applications 2018年10月28日 Engineering Sciences Society, IEICE
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...
Japan-Singapore Workshop on Coding and Information Theory 2018年3月4日 School of Physical & Mathematical Sciences, Nanyang Technological University
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...
