Abstract: A controllable pulse generator generates the pulses of the signal which are respectively contained in successive time windows, and a control device formulates a control signal for the generator including, for each pulse, an indication of its position in the corresponding window. The control device includes a processor to deliver for each time window, at a delivery frequency Fe greater than the pulse repetition frequency, successive groups of N bits together defining a digital cue of position of a pulse inside the window. Also, a converter converts this digital position cue into the control signal temporally spread over the length (T) of the window and including the indication of position at an instant corresponding to the digital position cue. This makes it possible to position the pulse inside its window with a temporal precision equal to 1/N.Fe.

Abstract: Successive groups of N bits are delivered at a delivery frequency Fe greater than a predetermined frequency PRF. At least one of the successive groups includes at least one subgroup of at least one bit defining at least one digital cue of position and of shape of at least one base pulse within a window of length 1/PRF. This digital cue is converted into the base pulse, and the base pulse is filtered using a high-pass filter for providing a pulse of the ultra wideband type within the window with a temporal accuracy equal to 1/N*Fe.

Abstract: An incident pulse signal of the ultra wideband type conveys digital information that is coded using pulses having a known theoretical shape. A decoding device includes an input for receiving the incident signal, and for delivering a base signal. A comparator receives the base signal and delivers an intermediate signal representative of the sign of the base signal with respect to a reference. A sampling circuit samples the intermediate signal for delivering a digital signal. A digital processing circuit correlates the digital signal with a reference correlation signal corresponding to a theoretical base signal arising from the reception of a theoretical pulse having the known theoretical shape.
