Low Density Parity Check Codes Constructed from Hankel Matrices

open access: yesJournal 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.

Evaluation of Low Density Parity Check Codes Over Various Channel Types [PDF]

open access: yesEngineering and Technology Journal, 2011
Low density parity check (LDPC) codes are one of the best error correcting codes in today’s coding world and are known to approach the Shannon limit. As with all other channel coding schemes, LDPC codes add redundancy to the uncoded input data to make it

Blind recognition of sparse parity‐check matrices of low‐density parity‐check codes in the presence of noise

open access: yesIET Communications, 2023
This paper studies the blind recognition method of the sparse parity‐check matrices of low‐density parity‐check codes in noncooperative communication, which is critical to the reverse analysis of communication protocols using LDPC codes.

Quantum dialogue protocol based on self-dual quantum low density parity check codes

open access: yes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.

A New Method for Building Low-Density-Parity-Check Codes

open access: yesInternational 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 ...

Reversible Low-Density Parity-Check Codes

open access: yesIEEE 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.

Spatially Coupled Generalized Low-Density Parity-Check Codes Over Class-A Impulsive Noise Channels

open access: yesIEEE 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

open access: yesIEEE 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.

Amalgamated Generalized Low Density Parity Check and Luby Transform Codes for the Wireless Internet [PDF]

open access: yes, 2007
Luby Transform codes (LT) were originally designed for the Binary Erasure Channel (BEC) encountered owing to randomly dropped packets in the statistical multiplexing aided Internet, where transmitted packets are not affected by the fading or noise of the
