Abstract:
Method of decoding a received systematic code encoded block corresponding to an original block of information, said received encoded block (RENCB) including soft systematic values, said method comprising detecting (13) whether or not said received encoded block is considered in error, performing a decoding (15) of said received encoded block for retrieving said original block of information (BIF) if said received encoded block is considered in error, and processing only said soft systematic values (16) for retrieving said original block (BIF) of information if said received encoded block is not considered in error.
Abstract:
A first wireless device (WAP1) belongs to a wireless communication system and is adapted to exchange information within at least a first band of frequencies. The method comprises detecting the eventual presence of at least one potential victim device (XDVC) operating within the first band of frequencies and reducing the interferences with said at least one potential victim device. Said first wireless device is provided with an antenna array (ANRR), and said detecting step comprises analyzing on said first wireless device the environment of the wireless device through said antenna array, and if said at least one potential victim device (XDVC) is detected, said interference reducing step comprises controlling the antenna array for steering the antenna beam towards an area located outside of the vicinity of said potential victim device for eventually exchanging information within said first band of frequencies with at least a second wireless device (WAP2) located in said area. The main embodiment uses Ultra Wide Band transmission known as UWB.
Abstract:
Method for transmitting information in a multi-band OFDM system, comprising delivering according to a given communication standard an initial data stream (IDS) , splitting (11) said initial data stream into a chosen number of elementary data streams and simultaneously transmitting (12) said elementary data streams according to said communication standard on said communication medium (MD) within different respective sub-bands (SBi) . These sub-bands all blong to the same band group. Proposal based on the MBOA standard.
Abstract:
On échantillonne la parole de façon à obtenir des trames vocales successives comportant chacune un nombre prédéterminé d'échantillons, et à chaque trame vocale on détermine des paramètres d'un modèle de prédiction linéaire à excitation par code, ces paramètres comportant un mot numérique d'excitation à long terme extrait d'un répertoire codé adaptatif, ainsi qu'un mot d'excitation à court terme extrait d'un répertoire codé fixe. L'extraction du mot d'excitation à long terme s'effectue en utilisant un premier filtre de pondération perceptuelle comportant un premier filtre de pondération formantique (FPP1). On effectue l'extraction du mot d'excitation à court terme en utilisant le premier filtre de pondération perceptuelle (FPP1) cascadé à un deuxième filtre de pondération perceptuelle comportant un deuxième filtre de pondération formantique (FPP2). Le dénominateur de la fonction de transfert du premier filtre de pondération formantique est égal au numérateur du deuxième filtre de pondération formantique.
Abstract:
On échantillonne la parole de façon à obtenir des trames vocales successives comportant chacune un nombre prédéterminé d'échantillons, et à chaque trame vocale on détermine des paramètres d'un modèle de prédiction linéaire à excitation par code, ces paramètres comportant un mot numérique d'excitation à long terme (v i ) extrait d'un répertoire codé adaptatif (DLT) et un gain à long terme associé (Ga), ainsi qu'un mot d'excitation à court terme (cj) extrait d'un répertoire codé fixe (DCT) en utilisant un filtrage numérique de prédiction linéaire (FP), et un gain à court terme associé (Gc). On met à jour le répertoire codé adaptatif à partir du mot d'excitation à long terme extrait et du mot d'excitation à court terme extrait, et on met à jour l'état du filtre de prédiction linéaire (FP) avec le mot d'excitation à court terme filtré par un filtre (FLT1) d'ordre supérieur ou égal à 1 dont les coefficients dépendent de la valeur du gain à long terme, de façon à affaiblir la contribution de l'excitation à court terme lorsque le gain de l'excitation à long terme est supérieur à un seuil prédéterminé.
Abstract:
The present invention is related to the realization of a simplified bottom electrode stack for high-density ferroelectric memory cells, where the ferroelectric capacitor is positioned directly on top of the contact plug. The ferroelectric layer is formed a low partial oxygen pressure to maintain the bottom electrode in its metallic form.
Abstract:
The method of processing an incident multi-carrier signal comprises receiving said incident signal (ISG) and performing a reception processing including an equalization processing (13) providing a first signal (AUX). It further comprises detecting (16) eventual interferences within said incident signal, said interferences detecting being performed in the frequency domain on a second signal obtained from said first signal.
Abstract:
The invention relates to a colour-filter array (1) for an optical-image sensor comprising pixels (2) that are arranged in a matrix or a line, each pixel being connected to an electronic circuit for converting the information concerning the luminosity of each pixel (2) into electric signals. A rectangular colour filter (3) of a predetermined colour (R, G, B) is placed over each pixel (2) and several pixels (2) that are directly adjacent form pixel by pixel with colour filters (3) of different colours a base cell, a plurality of said base cells together constituting the matricial or linear image sensor. The aim of the invention is to create a colour filter array for an optical-image sensor, which reliably prevents the falsification of the colour signals by unfiltered white light. To achieve this, the border regions (4) between adjacent colour filters (3) of different colours are significantly less permeable to light as a result of an overlap (5) or additional non-transparent strips (6).
