Low Density Parity Check Codes Constructed from Hankel Matrices
Journal of Telecommunications and Information Technology, 2018 In this paper, a new technique for constructing low density parity check codes based on the Hankel matrix and circulant permutation matrices is proposed. The new codes are exempt of any cycle of length 4.

Quantum dialogue protocol based on self-dual quantum low density parity check codes
网络与信息安全学报, 2020 In quantum channels, particles are usually affected by noise during transmission. A quantum dialogue protocol based on self-dual quantum low density parity check codes was proposed to resist noise attacks.

Reversible Low-Density Parity-Check Codes
IEEE Transactions on Information Theory, 2009 Low-density parity-check (LDPC) codes may be decoded using a circuit implementation of the sum-product algorithm which maps the factor graph of the code. By reusing the decoder for encoding, both tasks can be performed using the same circuit, thus reducing area and verification requirements.

A New Method for Building Low-Density-Parity-Check Codes
International Journal of Technology, 2019 This paper proposes a new method for building low-density-parity-check codes, exempt of cycle of length 4, based on a circulant permutation matrix, which needs very little memory for storage it in the encoder and a dual diagonal structure is applied ...

Spatially Coupled Generalized Low-Density Parity-Check Codes Over Class-A Impulsive Noise Channels
IEEE Access, 2019 In this paper, a class of spatially coupled generalized low-density parity-check (SC-GLDPC) codes with minimum coupling width is introduced to mitigate the Class-A impulsive noise. Codes with minimum coupling width are beneficial to simple code structure,

Fifteen Years of Quantum LDPC Coding and Improved Decoding Strategies
IEEE Access, 2015 The near-capacity performance of classical low-density parity check (LDPC) codes and their efficient iterative decoding makes quantum LDPC (QLPDC) codes a promising candidate for quantum error correction.

ON THE CLASS OF ARRAY-BASED APM-LDPC CODES [PDF]
Journal of Algebraic Systems, 2021 We construct an explicit class of affine permutation matrix low-density parity-check (APM-LDPC) codes based on the array parity-check matrix by using two affine maps f (x) = x-1 and g(x) = 2x-1 on Z_m, where m is an odd prime number, with girth 6 and ...

On the Stopping Distance of SA-LDPC Codes by Transversal Designs
IEEE Access, 2018 In this paper, we analyze the size of the smallest stopping set (called the stopping distance) for the parity-check matrix of a superposed array low-density parity-check (SA-LDPC) code for column weights 3 and 4 by using the transversal design (TD ...

An Efficient Construction Method for Quasi-Cyclic Low Density Parity Check Codes
IEEE Access, 2017 In this paper, we propose an optimized belief propagation (OBP) based progressive edge-growth (PEG) method for constructing quasi-cyclic low density parity check (QC-LDPC) codes. In this proposed method, Tanner graphs are built by progressively appending
