MDS or NMDS self-dual codes from twisted generalized Reed-Solomon codes [PDF]
arXiv, 2020 Self-dual maximum distance separable codes (self-dual MDS codes) and self-dual near MDS codes are very important in coding theory and practice. Thus, it is interesting to construct self-dual MDS or self-dual near MDS codes. In this paper, we not only give check matrices of dual codes of twisted generalized Reed-Solomon codes (TGRS codes) but also ...

Shortened Array Codes of Large Girth
, 2006 One approach to designing structured low-density parity-check (LDPC) codes with large girth is to shorten codes with small girth in such a manner that the deleted columns of the parity-check matrix contain all the variables involved in short cycles. This

Simplified Trellis Min–Max Decoder Architecture for Nonbinary Low-Density Parity-Check Codes
IEEE Transactions on Very Large Scale Integration (VLSI) Systems, 2015 Nonbinary low-density parity-check (NB-LDPC) codes have become an efficient alternative to their binary counterparts in different scenarios, such as moderate codeword lengths, high-order modulations, and burst error correction.

AI Coding: Learning to Construct Error Correction Codes [PDF]
arXiv, 2019 In this paper, we investigate an artificial-intelligence (AI) driven approach to design error correction codes (ECC). Classic error correction code was designed upon coding theory that typically defines code properties (e.g., hamming distance, subchannel reliability, etc.) to reflect code performance.

Twisted Reed-Solomon Codes With One-dimensional Hull [PDF]
arXiv, 2020 The hull of a linear code is defined to be the intersection of the code and its dual. When the size of the hull is small, it has been proved that some algorithms for checking permutation equivalence of two linear codes and computing the automorphism group of a linear code are very effective in general.

Low-density parity-check codes
IRE Transactions on Information Theory, 1962 A low-density parity-check code is a code specified by a parity-check matrix with the following properties: each column contains a small fixed number j \geq 3 of l's and each row contains a small fixed number k > j of l's. The typical minimum distance of

Efficient LDPC Code Design based on Genetic Algorithm for IoT Applications
EAI Endorsed Transactions on Industrial Networks and Intelligent SystemsIn this paper, we propose a low-density parity check (LDPC) code design scheme that improves the performance of the existing genetic algorithm-based LDPC scheme. In particular, we enhance the performance of the LDPC code by removing the girth-4 property
