5G-NR PRACH Detection Using an AutoEncoder Under Interference
Ahmed Sawadogo, Désiré Guel, Boureima Zerbo
Efficient detection of the Physical Random Access Channel (PRACH) is vital for reliable initial access in 5G New Radio (5G-NR), yet it remains challenged by intra- and inter-cell interference. This paper proposes a deep learning-based solution leveraging an Autoencoder (AE) trained on synthetic PRACH data under noisy conditions. The model dete(...)

Effects of information asymmetry and political governance on Total factor productivity in the WAEMU
Adama Ouédraogo, Inoussa Traoré, Ousmane Traoré, Idrissa M. Ouédraogo
Improving total productivity (TFP) is a major challenge within the West African Economic and Monetary Union (WAEMU). Despite research on the determi-nants of TFP in sub-Saharan Africa and other regions, certain factors that ex-plain TFP, such as information asymmetry and governance, warrant attention in the WAEMU context. This paper analyzes t(...)

Fourier multipliers and Sobolev spaces on homogeneous spaces related to Gelfand pairs
Yaogan Mensah, Marie Francoise Ouedraogo
Let G be a locally compact Hausdorff group and let K be a compact subgroup of G such that (G,K) is a Gelfand pair. This paper is devoted to the study of Fourier multipliers and Sobolev spaces on the homogeneous space G/K. The Fourier multipliers and the Sobolev spaces on G/K are built from a vector-valued Fourier transformation related to unit(...)

Investigation of SnS thin film as a BSF layer in Cu2ZnSnS4-based solar cells: a strategy to improve efficiency using SCAPS-1D
Y. Coulibaly,* , S. Ouedraogo, D. Oubda, R. Sam, F. Zougmore
Photovoltaic devices based on the quaternary material Copper-Zinc-Tin-Sulfide (Cu2ZnSnS4) commonly called CZTS have shown promising conversion efficiency in the last decade. However, this conversion efficiency still remains below expectations due to several factors including the high recombination rate at the CZTS/Mo rear contact. Indeed, this(...)

A Comparative Study of CDL/TDL Channel Models in 5G-mmWave Networks
Mahamadi Sogoba, Désiré Guel, Boureima Zerbo
Millimeter-wave (mmWave) bands play a key role in 5G New Radio (5G-NR). They provide wider bandwidth and support much higher data rates. However, these bands also bring serious challenges. Signal propagation is more complex and affects system performance. This study fills an important gap. It compares two standard 3GPP channel models: Clustere(...)

Introduction: Low yield is often claimed as one of the most important challenges for Bambara groundnut production in West Africa. To address the lack of high-yielding genotypes of Bambara groundnut in Burkina Faso, participatory evaluation and selection through multilocation trials is an important step to be taken. The present study aims at th(...)

Political Reforms and Persistent Democratic Issues in Togo: What Implications for the Commonwealth? Réformes politiques et problèmes démocratiques persistants au Togo : quelles implications pour le Commonwealth ?
Mahamadi OUEDRAOGO & Lalbila Aristide YODA
Depuis son indépendance de la France en 1960, le Togo a connu plusieurs crises politiques, à
commencer par un coup d’État militaire en 1963, suivi d’un autre en 1967, qui a permis à la famille Gnassingbé
de consolider son pouvoir. Par le biais de révisions constitutionnelles et d’un contrôle étroit des processus
électoraux, cette famille(...)

Expérience du Burkina Faso dans la prise en charge des patients infectés chroniques par le VHB
Prof. Sombié Roger, Prof. Ag GUINGANE Nanelin Alice
Les recommandations de l’OMS de 2024 préconisent de traiter par du Ténofovir (TDF) plus de personnes infectées par le VHB en Afrique sub-saharienne parce que la majorite des cas de cirrhose et de cancer du foie proviennent de cette partie du monde. Cependant ces recommandations sont peu utilisées et mériteraient d'être contextualisées en se ba(...)
