Construction of regular quasi-cyclic protograph LDPC codes based on Vandermonde matrices
, 2008 In this contribution, we investigate the attainable performance of quasi-cyclic (QC) protograph Low-Density Parity-Check (LDPC) codes for transmission over both Additive White Gaussian Noise (AWGN) and uncorrelated Rayleigh channels.

Adaptive Offset Min‐Sum Decoder for 5G‐NR BG2 LDPC Codes Using Genetic Algorithm
Applied Computational Intelligence and Soft Computing, Volume 2026, Issue 1, 2026.This paper proposes a more efficient resource‐constrained decoding algorithm for Adaptive Offset Min‐Sum (A‐OMS) low‐density parity check (LDPC) optimized decoder parameters in fifth‐generation New Radio (5G‐NR) Base Graph 2 codes (BG2). To curb the challenge of observing the all‐time finest offset to use the irregular BG2 structure, a genetic ...

Advanced Science, Volume 12, Issue 18, May 15, 2025.This study identifies TREM2+ macrophages as key contributors to pathological bone formation in ankylosing spondylitis (AS). These macrophages mediate pathological new bone formation via the CREG1‐IGF2R‐PI3K‐AKT pathway and are regulated by IL‐33 through STAT6 phosphorylation.

Concatenated Turbo/LDPC codes for deep space communications: performance and implementation [PDF]
, 2013 Deep space communications require error correction codes able to reach extremely low bit-error-rates, possibly with a steep waterfall region and without error floor. Several schemes have been proposed in the literature to achieve these goals.

Classical channel bandwidth requirements in continuous variable quantum key distribution systems
IET Quantum Communication, Volume 5, Issue 4, Page 601-611, December 2024.The reconciliation method for continuous variable quantum key distribution (CV‐QKD) systems is usually chosen based on its reconciliation efficiency. Nonetheless, one must also consider the requirements of each reconciliation method in terms of the amount of information transmitted on the classical channel. Such may limit the achievable key rates.

QC-LDPC code-based cryptography
, 2014 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 public-key cryptosystems derived from the McEliece and Niederreiter schemes.

A Note on the Girth of (3, 19)-Regular Tanner’s Quasi-Cyclic LDPC Codes
IEEE Access, 2021 In this article, we study the cycle structure of (3, 19)-regular Tanner’s quasi-cyclic (QC) LDPC codes with code length $19p$ , where $p$ is a prime and $p\equiv 1~(\bmod ~57)$ , and transform the conditions for the existence of cycles of ...
