Generalized Belief Propagation to break trapping sets in LDPC codes [PDF]

open access: yes, 2014
6 pagesInternational audienceIn this paper, we focus on the Generalized Belief Propagation (GBP) algorithm to solve trapping sets in Low-Density Parity-Check (LDPC) codes.

High-Throughput Multi-Frame Decoding of QC-LDPC Codes With Modified Rejection-Based Minimum Finding

open access: yesIEEE Access, 2022
The key computation in the min-sum decoding algorithm of a Low-Density Parity-Check (LDPC) is finding the first two minima and also the location of the first minimum among a set of messages passed from Variable Nodes (VNs) to Check Nodes (CNs) in a ...

Tree-structure Expectation Propagation for Decoding LDPC codes over Binary Erasure Channels [PDF]

open access: yes, 2010
Expectation Propagation is a generalization to Belief Propagation (BP) in two ways. First, it can be used with any exponential family distribution over the cliques in the graph.

Wire Codes [PDF]

open access: yesQuantum
Quantum information is fragile and must be protected by a quantum error-correcting code for large-scale practical applications. Recently, highly efficient quantum codes have been discovered which require a high degree of spatial connectivity. This raises

Finite Rate QLDPC-GKP Coding Scheme that Surpasses the CSS Hamming Bound [PDF]

open access: yesQuantum, 2022
Quantum error correction has recently been shown to benefit greatly from specific physical encodings of the code qubits. In particular, several researchers have considered the individual code qubits being encoded with the continuous variable ...

Minimum Distance Distribution of Irregular Generalized LDPC Code Ensembles

open access: yes, 2013
In this paper, the minimum distance distribution of irregular generalized LDPC (GLDPC) code ensembles is investigated. Two classes of GLDPC code ensembles are analyzed; in one case, the Tanner graph is regular from the variable node perspective, and in ...

Deterministic Dense Coding and Faithful Teleportation with Multipartite Graph States

open access: yes, 2008
We proposed novel schemes to perform the deterministic dense coding and faithful teleportation with multipartite graph states. We also find the sufficient and necessary condition of a viable graph state for the proposed scheme.

Study of equivalent point-to-point transmission model for coded relay cooperations

open access: yesTongxin xuebao, 2012
LDPC-coded relay cooperation and its joint iterative decoding based on the bi-layer Tanner graph were investigated.The coded relay cooperation becomed an equivalent and relatively simple point-to-point transmission model by introducing the notation of ...

Algebraic Optimization of Binary Spatially Coupled Measurement Matrices for Interval Passing

open access: yes, 2018
We consider binary spatially coupled (SC) low density measurement matrices for low complexity reconstruction of sparse signals via the interval passing algorithm (IPA).
