Efficient Decoding of Turbo Codes with Nonbinary Belief Propagation
EURASIP Journal on Wireless Communications and Networking, 2008 This paper presents a new approach to decode turbo codes using a nonbinary belief propagation decoder. The proposed approach can be decomposed into two main steps.

Threshold Analysis of Non-Binary Spatially-Coupled LDPC Codes with Windowed Decoding
, 2014 In this paper we study the iterative decoding threshold performance of non-binary spatially-coupled low-density parity-check (NB-SC-LDPC) code ensembles for both the binary erasure channel (BEC) and the binary-input additive white Gaussian noise channel (

International Journal of Finance &Economics, EarlyView.ABSTRACT This study draws on framing theory to investigate how microfinance institutions (MFIs) strategically construct a vulnerability‐oriented organisational identity and how this framing influences their funding decisions during the pre‐campaign phase of prosocial crowdfunding.

Entropy, 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 ...

ETRI Journal, 2023 This paper proposed a novel method for constructing quasi-cyclic low-density parity-check (QC-LDPC) codes of medium to high code rates that can be applied in cloud data storage systems, requiring better error correction capabilities.

Construction of Short-length High-rates Ldpc Codes Using Difference Families [PDF]
, 2007 Low-density parity-check (LDPC) code is linear-block error-correcting code defined by sparse parity-check matrix. It isdecoded using the massage-passing algorithm, and in many cases, capable of outperforming turbo code.

Permutation Decoding and the Stopping Redundancy Hierarchy of Linear Block Codes
, 2007 We investigate the stopping redundancy hierarchy of linear block codes and its connection to permutation decoding techniques. An element in the ordered list of stopping redundancy values represents the smallest number of possibly linearly dependent rows ...

Fast bootstrap and reliable readout using hidden references for DNA data storage
iMeta, EarlyView.This study provides a bootstrap readout framework for DNA data storage based on multiple‐fold hidden references. We employ a multi‐stage alignment and error correction strategy, transforming the de novo readout into a resequencing‐like workflow. Correlation to the hidden watermark reference identifies low‐error‐rate reads, and bit‐wise consensus ...

Periodontal diseases and adverse pregnancy outcomes. Present and future
Periodontology 2000, EarlyView., 2023 Abstract For more than two decades the possible association between periodontal diseases and adverse pregnancy outcomes has been extensively evaluated. Numerous observational, intervention, and mechanistic studies have offered valuable information on this topic.

ITERATIVE DECODING OF SHORT LOW-DENSITY PARITY-CHECK CODES BASED ON DIFFERENTIAL EVOLUTION
Informatyka, Automatyka, Pomiary w Gospodarce i Ochronie ŚrodowiskaTo ensure a given quality of service in the networks of the Internet of Things, short error-correcting codes are used, in particular, low-density parity-check codes.
