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： The invention concerns a multi-channel pulsed UWB receiver (400). The receiver comprises a first stage (420) for translating the received signal to a baseband or intermediate frequency, a second stage (430) performing a quadrature mixing on the in-phase and quadrature channels of the first stage, a third stage (440) performing an integration, over a time window, of the signals from the second stage, and a fourth stage (450) combining the results of the integration of the third stage in order to provide the real part and the imaginary part of the modulation symbol. The receiver can be configured (figures 4A-4H) depending on the receiving channel and the type of treatment selected.

摘要： The invention relates to a UWB receiver with time drift correction. Following frequency translation by a quadrature demodulator (240), the received UWB pulsed signal is integrated over successive time windows (260) and subsequently sampled (270). A phase shift estimator (280) determines the phase difference between samples separated by a multiple of the sampling period approximating the period of the pulses of the signal. On the basis of the phase difference, control means (290) deduce a time shift to be applied to the integrators (260) in order to synchronise the receiver in relation to the received signal.

摘要： Ce filtre électronique coupe-bande (10) est apte à recevoir un signal d'entrée (Xe) et à délivrer un signal filtré (E) présentant, en une fréquence de coupure (Fc), une amplitude atténuée par rapport à celle du signal d'entrée (Xe).
Il comprend un module (12) d'intégration du signal d'entrée lors de plusieurs fenêtres temporelles successives, chaque fenêtre temporelle débutant en un instant temporel initial respectif et ayant une durée sensiblement égale à l'inverse de la fréquence de coupure (Fc), les instants temporels initiaux d'au moins deux fenêtres distinctes étant séparés d'un décalage temporel de valeur supérieure ou égale à une durée prédéfinie de référence, chaque intégration du signal d'entrée (Xe) lors d'une fenêtre temporelle respective résultant en un signal intermédiaire (Si) respectif; et un module (16) de sommation des signaux intermédiaires (Si) issus du module d'intégration (12) ; le signal filtré (E) étant fonction de la somme desdits signaux intermédiaires (Si).

摘要： The invention relates to ultrawide-band pulse generators, particularly for radio communication at frequencies of 2 to 11 GHz. The generator includes an oscillator, providing an output signal at a carrier frequency F
0 , followed by a radiofrequency switching transistor (SW, SW') and a control circuit (CTRL) that controls the gate of the transistor so as to make said transistor conductive for a duration T corresponding to the desired duration of an UWB pulse. The control circuit is arranged so as to consecutively apply, during a single UWB pulse, a first gate voltage V
L that makes the transistor conductive with a first internal resistance value during a first portion of the duration T, then at least one second gate voltage that makes the transistor conductive with a second internal resistance value, different from the first value, during a second portion of the duration T. Said internal resistances cause a different attenuation of the oscillation, during the duration T of the pulse, thus enabling the spectrum of the pulse to be controlled so as to help keep same within the spectrum sizes set by radio communication standards.

摘要： The invention relates to an integrator circuit with multiple time window functions for carrying out a plurality of integration operations in parallel, each integration operation being carried out in a coherent manner over a sequence of time windows including at least one such window. The circuit includes a plurality of integration paths each corresponding to an integration operation. The integration paths share a same voltage/current converter and same first switching means for switching the signal to be integrated at the input of said converter, each integration path further including at least one integration capacitor mounted in counter-reaction to a functional amplifier and receiving the resulting current via second switching means for selecting said path.
