Explicit construction of girth-eight QC-LDPC codes and its application in CRT method

open access: yesTongxin xuebao, 2012
For arbitrary code lengths of the form PL(P≥3L<sup>2</sup>/4+L-1),a new family of (4,L)-regular quasi-cyclic (QC) low-density parity-check (LDPC) codes was proposed explicitly with girth ight.Employing the new code as a component code in the ...

Assessing disturbances in surviving primary forests of Europe

open access: yesConservation Biology, Volume 39, Issue 2, April 2025.
Abstract Primary forests are of paramount importance for biodiversity conservation and the provision of ecosystem services. In Europe, these forests are scarce and threatened by human activities. However, a comprehensive assessment of the magnitude of disturbances in these forests is lacking, due in part to their incomplete mapping.
