Bit-Metric Decoding of Non-Binary LDPC Codes with Probabilistic Amplitude Shaping

open access: yes, 2018
A new approach for combining non-binary low-density parity-check (NB-LDPC) codes with higher-order modulation and probabilistic amplitude shaping (PAS) is presented.

Does induction or augmentation of labor increase the risk of postpartum hemorrhage in pregnant women with anemia? A multicenter prospective cohort study in India

open access: yesInternational Journal of Gynecology &Obstetrics, Volume 169, Issue 1, Page 299-309, April 2025.
Abstract Objective To investigate whether induction/augmentation of labor in pregnant women with anemia increases the risk of postpartum hemorrhage (PPH) and whether this risk varied by indications for labor induction/augmentation and by anemia severity in pregnancy.

Digital image information hiding algorithm research based on LDPC code

open access: yesEURASIP Journal on Image and Video Processing, 2018
LDPC (low-density parity-check code) is a parity check code, and its performance is very close to Shannon limit. It is a sort of good channel code which has good ability of error correction. The coding can be introduced to an information-hiding algorithm

On Girth Conditioning for Low-Density Parity-Check Codes [PDF]

open access: yesIEEE Transactions on Communications, 2011
Low-density parity-check (LDPC) codes are gaining interest for high data rate applications in both terrestrial and spatial communications. They can be designed and studied through a bipartite graph whose characteristics affect the performance. This paper proposes a low-complexity method to improve the performance of LDPC codes by selectively removing ...

Threshold Analysis of Non-Binary Spatially-Coupled LDPC Codes with Windowed Decoding

open access: yes, 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 (

What Explains International Interest Rate Co‐Movement?

open access: yesJournal of Applied Econometrics, EarlyView.
ABSTRACT The international co‐movement of interest rates reflects correlated business‐cycle fluctuations, largely driven by demand shocks. Monetary policy in advanced economies follows domestic mandates—inflation and the output gap—and does not respond to foreign policy shocks.

Analisa Performansi Low Density Parity Check Code Pada Sistem CDMA [PDF]

open access: yes, 2011
The purpose of this final project is to analyze the performance of Low Density Parity Check Code for CDMA system. The analyze is to compare the simulation program of LDPC-CDMA with different parity check matrix LDPC and different amount of active user ...

Check-hybrid GLDPC Codes: Systematic Elimination of Trapping Sets and Guaranteed Error Correction Capability

open access: yes, 2016
In this paper, we propose a new approach to construct a class of check-hybrid generalized low-density parity-check (CH-GLDPC) codes which are free of small trapping sets.

Trends in the incidence of attention deficit hyperactivity disorder in children and early risk factors

open access: yesJCPP Advances, EarlyView.
Abstract Background Few studies have used nationwide registry data from both primary and secondary healthcare services to examine the incidence of attention‐deficit/hyperactivity disorder (ADHD) in children while accounting for early risk factors. We aimed to investigate trends in ADHD diagnoses and associated risk factors.

Efficient LDPC Code Design based on Genetic Algorithm for IoT Applications

open access: yesEAI Endorsed Transactions on Industrial Networks and Intelligent Systems
In this paper, we propose a low-density parity check (LDPC) code design scheme that improves the performance of the existing genetic algorithm-based LDPC scheme. In particular, we enhance the performance of the LDPC code by removing the girth-4 property
