Nonlinear Channel Estimation for OFDM System by Complex LS-SVM under High Mobility Conditions
Anis Charrada, Abdelaziz Samet
A nonlinear channel estimator using complex Least Square Support Vector Machines (LS-SVM) is proposed for pilot-aided OFDM system and applied to Long Term Evolution (LTE) downlink…
Stark Broadening of Carbon and Oxygen Lines in Hot DQ White Dwarf Stars: Recent Results and Applications
P. Dufour, N. Ben Nessib, S. Sahal-Bréchot +1
White dwarf stars are traditionally found to have surface compositions made primarily of hydrogen or helium. However, a new family has recently been uncovered, the so-called Hot DQ…
Speed Scaling on Parallel Processors with Migration
Eric Angel, Evripidis Bampis, Fadi Kacem +1
We study the problem of scheduling a set of jobs with release dates, deadlines and processing requirements (or works), on parallel speed-scaled processors so as to minimize the tot…
J-Class Abelian Semigroups of Matrices on C^n and Hypercyclicity
Adlene Ayadi, Habib Marzougui
We give a characterization of hypercyclic finitely generated abelian semigroups of matrices on C^n using the extended limit sets (the J-sets). Moreover we construct for any n\geq 2…
