This correspondence presents a method for constructing structured regular low-density
parity-check (LDPC) codes based on a special type of combinatoric designs, known as …

Two algebraic methods for systematic construction of structured regular and irregular low-
density parity-check (LDPC) codes with girth of at least six and good minimum distances are …

We adopt a class of quasi-cyclic low-density parity-check codes that allow to overcome the
main limitations of the original McEliece cryptosystem based on Goppa codes, that are large …

In this paper, a new variant of the McEliece cryptosystem, based on quasi-cyclic low-density
parity-check (QC-LDPC) codes, is studied. In principle, such codes can substitute Goppa …

This book describes the fundamentals of cryptographic primitives based on quasi-cyclic low-
density parity-check (QC-LDPC) codes, with a special focus on the use of these codes in …

(57) ABSTRACT A set of irregular LDPC (Low Density Parity Check) codes having a pseudo-
random structure and low encoding com plexity. A block-cyclic LDPC code has an irregular …

A matrix-theoretic approach for studying quasi-cyclic codes based on matrix transformations
via Fourier transforms and row and column permutations is developed. These …

This paper presents two novel low-complexity encoding algorithms for quasi-cyclic (QC)
codes based on Galois Fourier transform. The key idea behind them is making use of the …
