Repeat Accumulate Based Designs for LDPC Codes on Fading Channels [PDF]
arXiv, 2014 Irregular repeat-accumulate Root-Check LDPC codes based on Progressive Edge Growth (PEG) techniques for block-fading channels are proposed. The proposed Root-Check LDPC codes are {both suitable for channels under $F = 2, 3$ independent fadings per codeword and} for fast fading channels.

A Joint Optimization Technique for Multi-Edge Type LDPC Codes [PDF]
arXiv, 2016 This paper considers the optimization of multi-edge type low-density parity-check (METLDPC) codes to maximize the decoding threshold. We propose an algorithm to jointly optimize the node degree distribution and the multi-edge structure of MET-LDPC codes for given values of the maximum number of edge-types and maximum node degrees.

Jointed LDPC codes design for half-duplex relay channels
Tongxin xuebao, 2013 In order to increase the coding gain of decode-and-forward half-duplex relay channel, a jointed LDPC coding structure and its corresponding optimization scheme was proposed. Novel structure made the subcodes of both source and relay nodes as parts of the

Tanner (3, 23)-Regular QC-LDPC Codes: Cycle Structure and Girth Distribution
IEEE AccessThis paper studies a class of quasi-cyclic LDPC (QC-LDPC) codes, i.e., Tanner (3, 23)-regular QC-LDPC codes of code length $23p$ with $p$ being a prime and $p \equiv 1 (\mathrm {mod} 69)$ .
