Design and Performance of Rate-compatible Non-Binary LDPC Convolutional Codes
, 2011 In this paper, we present a construction method of non-binary low-density parity-check (LDPC) convolutional codes. Our construction method is an extension of Felstroem and Zigangirov construction for non-binary LDPC convolutional codes.

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

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 ...
