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.
