This article proposes an encoding method based on a two-step encoding algorithm for the 12 quasi-cyclic (QC)-low-density parity-check (LDPC) (QC-LDPC) codes specified in the IEEE 802.11n/ac/ax standards. The proposed approach jointly considers all co

The influence of mild thermal annealing and nickel addition on the magnetic properties of Co–CoO multilayers is investigated. Co–CoO and CoNi–CoNiO multilayers were fabricated by radio-frequency magnetron sputtering and natural oxidation. Their

In this work, a phononic metamaterial that could be applied for both acoustic and elastic wave attenuation is numerically examined. The hollow yablonovite structure with the addition of hollow spheres on a face-centered cubic arrangement is examined

Ultrathin Ag and Ni/NiO films are sequentially produced on Corning glass and silicon substrates by means of magnetron sputtering. Post annealing treatment in a furnace with air at [Formula: see text]C and [Formula: see text]C may lead to the formatio

Conventional bit-flipping (BF) algorithms spectacularly fail to handle punctured LDPC codes as they use hard decisions and, therefore, they cannot effectively cope with zero-reliability punctured symbols. However, BF techniques lead to low-cost high-

In this paper the impact of the approximation error on the decisions taken by LDPC decoders is studied. In particular, we analyze the mechanism, by means of which approximation error alters the decisions of a finite-word-length implementation of the

In this paper, a new theoretical model that describes the impact of the approximation error on the decisions taken by LDPC decoders is discussed. In particular, the theoretical model extends previous results and reconstructs the mechanism, by means o
