A Post-Quantum Digital Signature Scheme from QC-LDPC Codes [PDF]

open access: yes, 2022
We propose a novel post-quantum code-based digital signature algorithm whose security is based on the difficulty of decoding Quasi-Cyclic codes in systematic form, and whose trapdoor relies on the knowledge of a hidden Quasi-Cyclic Low-Density-Parity ...

Constructing Large Girth QC Protograph LDPC Codes Based on PSD-PEG Algorithm

open access: yesIEEE Access, 2017
For a given base graph, the lifted graph can be obtained by a copy-and-permute procedure. If the permutation is cyclic, the lifted graph corresponds to a quasi-cyclic (QC) protograph low-density parity-check (LDPC) code.

Reordered static layered schedule for 5G low‐density parity‐check codes

open access: yesElectronics Letters, Volume 60, Issue 7, April 2024.
A static layered schedule for the 5G low‐density parity‐check codes is proposed here. The proposed static layered schedule provides better error performance and faster convergence speed than state‐of‐the‐art. Abstract The error performance of the 5G low‐density parity‐check codes is significantly impacted by the update order of layers.

Some variations of Tanner's construction for short length QC‐LDPC codes

open access: yesElectronics Letters, Volume 60, Issue 3, February 2024.
We propose a variation of Tanner's construction for quasi‐cyclic low‐density parity‐check codes in a way that allows us to use NON‐prime lifting sizes by using some arithmetic sequences instead of geometric sequences. We prove two theorems on the values of this lifting sizes so that the resulting code has girth at least 8.

Construction of Rate-Compatible Raptor-Like Quasi-Cyclic LDPC Code With Edge Classification for IDMA Based Random Access

open access: yesIEEE Access, 2019
Recently, rate-compatible raptor-like quasi-cyclic low-density parity-check (RL-QC-LDPC) codes, which are a typical class of multi-edge type LDPC codes with excellent performance and high flexibility, have been adopted in the technical specification of ...

Energy‐Efficiency Maximization in Backscatter Communication‐Based Non‐Orthogonal Multiple Access System: Dinkelbach and Successive Convex Approximation Approaches

open access: yesIET Signal Processing, Volume 2024, Issue 1, 2024.
This paper investigates a backscatter communication (BackCom) based non‐orthogonal multiple access (NOMA) system in a multiple‐input and single‐output (MISO) scenario, where two decoding methods are deployed, including the sum‐capacity approach and QR decomposition.
