Abstract: L'invention concerne un procédé de localisation d'un objet, comprenant les étapes suivantes : émission (49) d'un premier signal par un premier émetteur affecté à l'objet et d'un second signal par au moins un second émetteur ; réception du premier et du second signal par au moins trois récepteurs ; dans chaque récepteur et pour le premier et le second signal : a) génération d'un premier et d'un second signal de référence ; b) corrélation (61) entre le premier signal et le premier signal de référence et entre le second signal et le second signal de référence ; c) interpolation (63) d'échantillons issus de la corrélation ; d) déduction du temps de propagation du premier et du second signal ; e) calcul de la différence entre les temps de propagation du premier et du second signal ; et par triangulation, déduction de la position de l'objet.

Abstract: The component has an integrated circuit (CI) including a super-heterodyne integrated tuner descending to a non null intermediary frequency with an input to receive terrestrial digital television signals. A band-pass filter (FBAW) delivers a filtered analogous signal with information conveyed by a desired channel. A digital block has an error correction stage to deliver a data packets flux corresponding to the information.

Abstract: The fault correction method between quadrature channels in a reception chain has a first calibration phase generating frequency calibration sets before transposition. In the reception step a correction is applied to the Fourier transform outputs with inverse amplitude and opposite phase.

Abstract: Component has integrated circuit (CI) with super-heterodyne integrated tuner descending to non null intermediary frequency with input (ESO) to receive television signals. First band-pass filter (FBAW) delivers filtered analogous signal containing information conveyed by desired channel. Second band-pass filter (FMMR) eliminates information of adjacent channels. Component has elements to determine central frequencies of both band-pass filters.

Inventor： PAILLE BRUNO , BONA MARIANO
Abstract: The device has a power control circuit (PCtrl) providing a control signal that takes signal presence and signal absence states representing presence and absence of a modulated signal, respectively. AND gate deactivates and activates demodulation circuits, to avoid their desynchronization and to enable rapid starting of demodulation when the control signal passes from the presence state to the absence state and vice versa, respectively. An independent claim is also included for a system for receiving a modulated signal, having a demodulator device.

Abstract: The method involves estimating a frequency shift of a carrier frequency of a received signal, with a frequency estimator (EST) in a manner to obtain an estimation value. The estimation value of the frequency shift is refined. The carrier frequency is corrected by a phase lock loop (PLL) initiated by the estimation value. The frequency locking range of the PLL is lower than the frequency locking range of the estimator. An independent claim is also included for a device for processing frequency shift.

Abstract: The circuit has a temporization device (221) with an input connected to an input and an output of a demodulator. A selection signal providing unit provides a selection signal (Sel) controlling a multiplexer (220) and a control device (222). A decoding circuit and another demodulator provide a decoded signal from a coded or modulated signal and corrected reputed parts of another decoded signal when the signal (Sel) is positioned for passing a signal provided by the device (221). An independent claim is also included for a decoding circuit.
