Comparison of Parallelization Strategies for Min-Sum Decoding of Irregular LDPC Codes
Tsinghua Science and Technology, 2013 Low-Density Parity-Check (LDPC) codes are powerful error correcting codes. LDPC decoders have been implemented as efficient error correction codes on dedicated VLSI hardware architectures in recent years.

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
