Low Complexity Decoding Algorithm of QC-LDPC Code
2010 IEEE Asia-Pacific Services Computing Conference, 2010Through the research on the decoding algorithm of low-density parity-check (LDPC) code, a low complexity decoding algorithm suitable for quasi-cyclic LDPC (QC-LDPC) code is proposed in this paper. The algorithm adopts layered decoding (LD), and the sub-minimum is replaced by the sum of an optimal correction factor and the minimum during the process of ...

Combinatorial optimization for improving QC LDPC codes performance
2013 IEEE International Symposium on Information Theory, 2013Techniques for searching for good quasi-cyclic (QC) LDPC block codes of short and moderate lengths which are suitable for practical purposes are studied. To facilitate implementations only codes whose parity-check matrices having bidiagonal structure of their submatrices and consequently having low encoding complexity are considered.

A Network-Efficient Nonbinary QC-LDPC Decoder Architecture
IEEE Transactions on Circuits and Systems I: Regular Papers, 2012Nonbinary low-density parity-check (LDPC) codes are of great interest due to their better performance cover binary ones when the code length is moderate. However, the cost of decoder implementation for these LDPC codes is still very high. In this paper, a low-complexity VLSI architecture for nonbinary LDPC decoders is presented.

Efficient Decoding of QC-LDPC Codes Using GPUs
2011In this work, we propose an efficient quasi-cyclic LDPC (QCLDPC) decoder simulatorwhich runs on graphics processing units(GPUs). We optimize the data structures of the messages used in the decoding process such that both the read and write processes can be performed in a highly parallel manner by the GPUs.
