Research on unequal error protection of irregular LDPC codes

open access: yesTongxin xuebao, 2005
An irregular low-density parity-check (LDPC) code with unequal error protection (UEP) property was proposed. A weight-increasing parity-check (WIPC) matrix was constructed.

Low-rate coding using incremental redundancy for GLDPC codes [PDF]

open access: yes, 2008
In this paper we propose a low-rate coding method, suited for application-layer forward error correction. Depending on channel conditions, the coding scheme we propose can switch from a fixed-rate LDPC code to various low-rate GLDPC codes.

The Analytical Description of Regular LDPC Codes Correcting Ability

open access: yesTransport and Telecommunication, 2014
The analytical description of regular LDPC (Low-Density Parity Check) codes correcting ability has been investigated. The statistical dependencies for the maximum number of corrected bits per the code word as a function of LDPC code word length and code ...

COMPARATIVE ANALYSIS OF LDPC AND BCH CODES ERROR-CORRECTING CAPABILITIES

open access: yesInformation and Telecommunication Sciences, 2014
The error-correcting capabilities of regular LDPC (Low Density Parity Check) codes and BCH (Bose-Chaudhuri-Hocquenguem) codes are examined. The qualitative analysis and the quantitative assessment of error-correcting abilities are performed for LDPC ...

Non-binary protograph low-density parity-check codes for space communications

open access: yes, 2012
Protograph-based non-binary low-density parity-check (LDPC) codes with ultra-sparse parity-check matrices are compared with binary LDPC and turbo codes (TCs) from space communication standards.

Quasi-cyclic Generalized LDPC codes with low error floors

open access: yes, 2008
In this paper, a novel methodology for designing structured generalized LDPC (G-LDPC) codes is presented. The proposed design results in quasi-cyclic G-LDPC codes for which efficient encoding is feasible through shift-register-based circuits.

A Resource Efficient Ising Model‐Based Quantum Sudoku Solver

open access: yesSoftware: Practice and Experience, Volume 56, Issue 6, Page 643-657, June 2026.
ABSTRACT Background Quantum algorithms exploit superposition and parallelism to address complex combinatorial problems, many of which fall into the non‐polynomial (NP) class. Sudoku, a widely known logic‐based puzzle, is proven to be NP‐complete and thus presents a suitable testbed for exploring quantum optimization approaches.

Radiation‐Induced Fault Detection in Superconducting Quantum Devices

open access: yesAdvanced Quantum Technologies, Volume 9, Issue 4, April 2026.
Cosmic rays cause correlated errors in superconducting quantum computers. Quantum error correction codes are not sufficient to solve this issue, as such a real‐time logical detector for radiation faults has been developed. It identifies radiation faults with high accuracy, providing information which could be used to revert the effects of radiation and
