QC-LDPC Codes from Difference Matrices and Difference Covering Arrays
IEEE Access, 2022 Abstract We give a framework for generalizing LDPC code constructions that use Transversal Designs or related structures such as mutually orthogonal Latin squares. Our construction offers a broader range of code lengths and codes rates. Similar earlier constructions rely on the existence of finite fields of order a power of a prime. In contrast

Design and Analysis of Time-Invariant SC-LDPC Convolutional Codes With Small Constraint Length
, 2017 In this paper, we deal with time-invariant spatially coupled low-density parity-check convolutional codes (SC-LDPC-CCs). Classic design approaches usually start from quasi-cyclic low-density parity-check (QC-LDPC) block codes and exploit suitable ...

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

Relation Between GCD Constraint and Full-Length Row-Multiplier QC-LDPC Codes With Girth Eight
IEEE Communications Letters, 2021 The greatest-common-divisor (GCD) method is a general framework employing a set of simple inequalities (called GCD constraint) to guarantee girth eight for a class of $(J,L)$ quasi-cyclic (QC) low-density parity-check (LDPC) codes.
