Digital image information hiding algorithm research based on LDPC code
EURASIP 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]
IEEE 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 ...

Efficient LDPC Code Design based on Genetic Algorithm for IoT Applications
EAI Endorsed Transactions on Industrial Networks and Intelligent SystemsIn 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

PERBANDINGAN KINERJA LDPC PADA KANAL AWGN DENGAN MODULASI QPSK DAN BPSK [PDF]
, 2011 Low Density Parity Check (LDPC) codes are one class of linear block coding techniques. The name comes from the characteristics of the LDPC parity check matrix was that only contain a little bit of '1 'if compared with the number of bits of '0'.
