Deriving Good LDPC Convolutional Codes from LDPC Block Codes [PDF]

IEEE Transactions on Information Theory, 2010
Low-density parity-check (LDPC) convolutional codes are capable of achieving excellent performance with low encoding and decoding complexity. In this paper we discuss several graph-cover-based methods for deriving families of time-invariant and time ...

Randomly Punctured LDPC Codes [PDF]

IEEE Journal on Selected Areas in Communications, 2016
In this paper, we present a random puncturing analysis of low-density parity-check (LDPC) code ensembles. We derive a simple analytic expression for the iterative belief propagation (BP) decoding threshold of a randomly punctured LDPC code ensemble on the binary erasure channel (BEC) and show that, with respect to the BP threshold, the strength and ...

LDPC codes [PDF]

, 2021
Στα ψηφιακά συστήματα, η πληροφορία κωδικοποιείται σε ακολουθίες από 0και 1, που αντιστοιχούν στις δύο δυνατές καταστάσεις των τρανζίστορ, on - off, τα οποία λειτουργούν ως διακόπτες. Το πλεονέκτημα αυτό έχει επιφέρει σημαντικέςαλλαγές στον τρόπο επεξεργασίας της πληροφορίας.

Full-Length Row-Multiplier QC-LDPC Codes With Girth Eight and Short Circulant Sizes

IEEE Access, 2023
As a special case of a quasi-cyclic (QC) low-density parity-check (LDPC) code, a full-length row-multiplier (FLRM) QC-LDPC code is described by a compact exponent matrix based on two sequences of integers.

Nonbinary Spatially-Coupled LDPC Codes on the Binary Erasure Channel [PDF]

, 2012
We analyze the asymptotic performance of nonbinary spatially-coupled low-density parity-check (SC-LDPC) codes built on the general linear group, when the transmission takes place over the binary erasure channel.

High-Speed Reconciliation for CVQKD Based on Spatially Coupled LDPC Codes

IEEE Photonics Journal, 2018
The speed of continuous variable quantum key distribution is limited by the reconciliation efficiency and the reconciliation frame error rate (FER) in the reconciliation phase.

On Sparse Regression LDPC Codes

2023 IEEE International Symposium on Information Theory (ISIT), 2023
Belief propagation applied to iterative decoding and sparse recovery through approximate message passing (AMP) are two research areas that have seen monumental progress in recent decades. Inspired by these advances, this article introduces sparse regression LDPC codes and their decoding.
