An Efficient Construction Method for Quasi-Cyclic Low Density Parity Check Codes

open access: yesIEEE 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

Universal Adapters between Quantum Low-Density Parity Check Codes

open access: yesPRX Quantum
We propose the repetition code adapter as a way to perform joint logical Pauli measurements within a quantum low-density parity check (LDPC) codeblock or between separate such codeblocks, thus providing a flexible tool for fault-tolerant computation with

Cyclic Low Density Parity Check Codes With the Optimum Burst Error Correcting Capability

open access: yesIEEE Access, 2020
The paper presents a new scheme of cyclic codes suitable for the correction of burst errors. This is accomplished by the proper definition of their parity check polynomials in which the difference between orders of every two consecutive elements of the ...

An Efficient Method to Construct Parity-Check Matrices for Recursively Encoding Spatially Coupled LDPC Codes †

open access: yesEntropy, 2016
Spatially coupled low-density parity-check (LDPC) codes have attracted considerable attention due to their promising performance. Recursive encoding of the codes with low delay and low complexity has been proposed in the literature but with constraints ...

Interactive reconciliation with low-density parity-check codes [PDF]

open access: yes2010 6th International Symposium on Turbo Codes & Iterative Information Processing, 2010
Efficient information reconciliation is crucial in several scenarios, being quantum key distribution a remarkable example. However, efficiency is not the only requirement for determining the quality of the information reconciliation process. In some of these scenarios we find other relevant parameters such as the interactivity or the adaptability to ...
