Implementation for Two-Stage Hybrid Decoding for Low Density Parity Check (LDPC) Codes
International Journal of Computer Applications, 2013 ABSTRACT LDPC codes are gaining high attention in Channel Coding field these days. However, one of the main problems facing usage of these codes in communication systems is the high complexity decoding scheme that results in high decoding delay. Such delay is not acceptable in some applications that depend on time such as video transmission. This paper

An Efficient Construction Method for Quasi-Cyclic Low Density Parity Check Codes
IEEE Access, 2017 In this paper, we propose an optimized belief propagation (OBP) based progressive edge-growth (PEG) method for constructing quasi-cyclic low density parity check (QC-LDPC) codes. In this proposed method, Tanner graphs are built by progressively appending

Temperature Monitoring of Mass Concrete Structure Using Wireless Sensing System
Structural Control and Health Monitoring, Volume 2025, Issue 1, 2025.Rapid temperature changes during the early stages of mass concrete construction can cause thermal cracking, which negatively impacts structural integrity and longevity. Reliable temperature monitoring is essential for effective crack control. Traditional methods, such as manual inspections and wired structural health monitoring systems, are often ...

A High Throughput Implementation of QC-LDPC Codes for 5G NR
IEEE Access, 2019 Quasi-cyclic low-density parity-check (QC-LDPC) codes are the choice for data channels in the fifth generation (5G) new radio (NR). At the transmitter side, code bits from the QC-LDPC encoder are delivered to the rate matcher.

Online fountain code with an improved caching mechanism
IET Communications, Volume 18, Issue 20, Page 1813-1825, December 2024.By catching some selected encoded symbols discarded in the original online fountain codes and giving an optimal degree selection strategy of encoded symbols, the proposed online fountain code improves the receiving rules of the encoded symbols. The proposed online codes outperform the state‐of‐art online fountain codes in terms of overhead factors ...
