摘要： Embodiments of a method and a device are disclosed. In an embodiment, a method for operating an impulse radio ultra-wideband (IR-UWB) device is disclosed. The method involves acquiring a signal, integrating one or more synchronization symbols in a synchronization field of the signal to determine an initial channel impulse response (CIR) measurement, and detecting whether a start-of-frame delimiter (SFD) field of the signal is identified during integration. When the SFD field of the signal is identified, the method further involves ceasing integration of the one or more synchronization symbols, scaling the initial CIR measurement, and determining a final CIR measurement based on the scaled CIR measurement. When the SFD field is not identified, the method further involves incrementing a counter configured to count the number of the one or more synchronization symbols integrated, and continuing integration of the one or more synchronization symbols until the SFD field is identified.

摘要： An acquisition detector and method include a preamble detector configured to search in a plurality of symbols for a preamble match with a known preamble pattern when a power level of the input signal exceeds a determined noise threshold. The acquisition detector further includes a frame delimiter detector configured to search in the plurality of symbols for a frame delimiter match with a known frame delimiter pattern when the preamble match is identified and the power level of the input signal exceeds a determined noise threshold.

摘要： The invention relates to a method for determining the arrival time of a UWB pulse at a receiver. When the pulse is modulated at an RF frequency, the receiver comprises: a quadrature demodulator (330); a first correlation stage (351, 352) for correlating the signal in phase with the first and second signals of an orthogonal base over a time window and a second correlation stage (353, 354) for correlating the signal in quadrature with the first and second signals of the orthogonal base over the same window; a phase estimator (360) that estimates the phase of the signal received in the orthogonal base on the basis of the correlation results from the first and/or second correlation stage(s); and computing means (370) for determining the arrival time on the basis of the estimated phase.

摘要： L'invention concerne un procédé et un dispositif d'intégration de signaux émis depuis un émetteur (1) vers au moins un récepteur (3) Ultra Large Bande (ULB), caractérisé en ce que
- on initialise au préalable la mesure en estimant une dérive d'horloge ΔDH init initiale entre l'émetteur (1) et le récepteur (2),
- on réalise une boucle itérative lors de laquelle :
○ on réalise une étape d'intégration d'au moins un signal primaire reçu composé d'au moins deux échantillons lors de laquelle on réalise au moins une première intégration utilisant la dérive d'horloge estimée et au moins une deuxième et une troisième intégration respectivement augmentée et diminuée d'une valeur prédéterminée,

on sélectionne parmi lesdites au moins trois intégrations, celle qui maximise un critère de qualité, et on adapte, le cas échéant la dérive d'horloge à celle correspondant à l'intégration sélectionnée.
