Construction of Near-Optimum Burst Erasure Correcting Low-Density Parity-Check Codes

open access: yes, 2008
In this paper, a simple, general-purpose and effective tool for the design of low-density parity-check (LDPC) codes for iterative correction of bursts of erasures is presented.

Beyond salaries: Teachers' experiences of navigating early years education amid economic instability in Türkiye

open access: yesBritish Educational Research Journal, EarlyView.
Abstract The intersection of economic conditions and early years education has long been debated, particularly where financial constraints shape educational practice and professional realities. Türkiye, characterised by high inflation and structural vulnerabilities in purchasing power parity, provides a critical context for examining how economic ...

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.

Generalized LDPC Codes for Ultra Reliable Low Latency Communication in 5G and Beyond

open access: yesIEEE Access, 2018
Generalized low-density parity-check (GLDPC) codes, where single parity-check constraints on the code bits are replaced with generalized constraints (an arbitrary linear code), are a promising class of codes for low-latency communication.

Delay-Exponent of Bilayer Anytime Code

open access: yes, 2014
In this paper, we study the design and the delay-exponent of anytime codes over a three terminal relay network. We propose a bilayer anytime code based on anytime spatially coupled low-density parity-check (LDPC) codes and investigate the anytime ...

Does Climate Risk Affect Employment Decisions? International Evidence

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This study investigates the effect of climate risk on corporate employment decisions. Using a large sample from 41 countries, we find a positive association between climate risk and underinvestment in labor, notably manifesting as excessive employee layoffs.

On the Minimum Distance of Generalized Spatially Coupled LDPC Codes [PDF]

open access: yes, 2013
Families of generalized spatially-coupled low-density parity-check (GSC-LDPC) code ensembles can be formed by terminating protograph-based generalized LDPC convolutional (GLDPCC) codes.
