    Abstract: A signal transmitter may include a waveform synthesis circuit and a signal transmission circuit. The waveform synthesis circuit may store values of a reference waveform for a selected channel of the signal transmitter, and use the stored values to generate values of reference waveforms for one or more other channels of the signal transmitter. The waveform synthesis circuit may further include a sampling boost circuit to generate one or more additional values for the reference waveforms. The waveform transmission circuit may generate signals for the channels of the signal transmitter based at least in part on the values of the reference waveforms, and transmit the signals via one or more antennas.

    Abstract: A UWB impulse receiver including an RF stage followed by a baseband processing stage. The baseband processing stage includes a Rake filter including a plurality of time fingers, each finger including an integrator of the baseband signal during an acquisition window, a control module, and a detection module estimating the received symbols from the integration results. During a synchronization phase, the control module drives respective positions of the acquisition windows associated with the different fingers, to scan at a reception interval, the RF stage only operating, in a course of the synchronization phase, during the plurality of acquisition windows.

    Abstract: L'invention concerne un récepteur UWB impulsionnel comprenant un étage RF (501) suivi d'un étage de traitement en bande de base (502). L'étage de traitement en bande de base comprend un filtre Rake (550) présentant une pluralité de doigts temporels (551 1 ,...,551 K ), chaque doigt comprenant un intégrateur du signal en bande de base pendant une fenêtre d'acquisition, un module de contrôle (580), et un module de détection (590) estimant les symboles reçus à partir des résultats d'intégration. Pendant une phase de synchronisation, le module de contrôle (580) pilote les positions respectives des fenêtres d'acquisition associées aux différents doigts, de manière à balayer à un intervalle de réception, ledit étage RF ne fonctionnant, au cours de cette phase de synchronisation, que pendant ladite pluralité d'acquisition.
