Full textLes algorithmes de rehaussement de la parole à voie unique sont utilisés afin de réduire le bruit de fond d'un signal de parole bruité. Ils sont présents dans plusieurs appareils tels que les téléphones sans fil et les prothèses auditives. Dans l'approche bayésienne d'estimation de l'amplitude spectrale locale (Short-Time Spectral Amplitude - STSA) pour le rehaussement de la parole, un estimé de la STSA non bruitée est déterminé en minimisant l'espérance statistique d'une fonction de coût. Ce type d'estimateurs incluent le MMSE STSA, le β-SA, qui intègre un exposant comme paramètre de la fonction de coût, et le WE, qui possède un paramètre de pondération.Cette thèse étudie les estimateurs bayésiens du STSA avec pour objectifs d'approfondir la compréhension de leurs propriétés et de proposer de nouvelles fonctions de coût ainsi que de nouveaux modèles statistiques afin d'améliorer leurs performances. En plus d'une étude approfondie de l'estimateur β-SA pour les valeurs de β ≤ 0, trois nouvelles familles d'estimateur sont dévelopées dans cette thèse: le β-SA pondéré (Weighted β-SA - Wβ-SA), une famille d'estimateur du STSA généralisé et pondéré (Generalized Weighted STSA - GWSA) ainsi qu'une famille d'estimateur du STSA multi-dimensionnel.Le Wβ-SA combine l'exposant présent dans le β-SA et le paramètre de pondération du WE. Ses paramètres sont choisis en considérant certaines caractéristiques du système auditif humain ce qui a pour avantage d'améliorer la réduction du bruit de fond à hautes fréquences tout en limitant les distorsions de la parole à basses fréquences. Une généralisation de la structure commune des fonctions de coût de plusieurs estimateurs bayésiens du STSA est proposée à l'aide de la famille d'estimateur GWSA. Cette dernière permet une unification des estimateurs bayésiens du STSA et apporte une meilleure compréhensio

Full textIn this thesis, we will prove decorrelation estimates of eigenvalues for several models of random Schrödinger operators in dimension one, in the localized regime, provided we have Wegner estimates. This will allow us to study spectral statistics.We will begin with the presentation of the hypotheses needed in our proofs and the models under consideration.We will continue with the study of the Minami estimates, which can be seen as decorrelation estimates of close eigenvalues. We will show that, in dimension one and in the localized regime, they are the consequences of the Wegner estimates. The results proven here have a area of validity smaller than the usual Minami estimates, but it will suffice for our study.Next, we will study the decorrelation estimates of distant eigenvalues for the models under consideration. We will show that they are consequences of the Minami estimates and the Wegner estimates, in the localized regime. The proofs will be different from one model to another.Eventually, we will show that these results allow us to study spectral statistics in the localized regime. For instance, the decorrelation estimates will be used to prove that the local energy level statistics, taken at two distincts energy levels, converge weakly to two independent Poisson processes on $\R$ with intensity the Lebesgue measure
