On the Minimum Distance of Generalized Spatially Coupled LDPC Codes [PDF]
, 2013 Families of generalized spatially-coupled low-density parity-check (GSC-LDPC) code ensembles can be formed by terminating protograph-based generalized LDPC convolutional (GLDPCC) codes.

Construction of Quantum LDPC Codes From Classical Row-Circulant QC-LDPCs [PDF]
IEEE Communications Letters, 2016 Classical row-circulant quasi-cyclic (QC) low-density parity check (LDPC) matrices are known to generate efficient high-rate short and moderate-length QC-LDPC codes, while the comparable random structures exhibit numerous short cycles of length-4. Therefore, we conceive a general formalism for constructing nondual-containing Calderbank–Shor–Steane (CSS)

Binary Wyner-Ziv and CEO Problem Coding Under the Hamming Distortion Criterion [PDF]
International Journal of Industrial Electronics, Control and OptimizationIn this paper, we present a practical encoding and decoding scheme for the binary Wyner-Ziv problem based on graph-based codes. Our proposed scheme uses low-density generator-matrix (LDGM) codes in lossy source coding part and low-density parity-check ...

Full-Length Row-Multiplier QC-LDPC Codes With Girth Eight and Short Circulant Sizes
IEEE Access, 2023 As a special case of a quasi-cyclic (QC) low-density parity-check (LDPC) code, a full-length row-multiplier (FLRM) QC-LDPC code is described by a compact exponent matrix based on two sequences of integers.

4-CYCLE FREE APM LDPC CODES WITH AN EXPLICIT CONSTRUCTION [PDF]
Journal of Algebraic Systems, 2021 Recently, a class of low-density parity-check codes based on affine permutation matrices, called APM-LDPC codes, have been considered which have some advantages than quasi-cyclic (QC) LDPC codes in terms of minimum-distance, cycle distribution, and error-

Effective identification of dominant fully absorbing sets for Raptor-like LDPC codes
ETRI Journal, 2023 The error-rate floor of low-density parity-check (LDPC) codes is attributed to the trapping sets of their Tanner graphs. Among them, fully absorbing sets dominantly affect the error-rate performance, especially for short blocklengths.
