Abstract: PROBLEM TO BE SOLVED: To decode an incident pulse signal of the ultra wideband type through digital processing. SOLUTION: The incident pulse signal of the ultra wideband type conveys digital information encoded by using pulses in a known theoretical shape. A decoding device is equipped with an input means which receives the incident signal and sends a base signal out, a preprocessing means which is so adapted as to receive the base signal and sends out an intermediate signal representing the code of the base signal with respect to a reference, a means which samples an intermediate ISN signal and sends a digital signal out, a synchronizing means, a decoding means, and a digital processing means which is so adapted as to correlate the digital signal with a reference correlation signal corresponding to a theoretical base signal arising from the reception of the theoretical pulses having the known theoretical shape.

Abstract: PROBLEM TO BE SOLVED: To provide a method for controlling the transmission of a super-wideband position modulation pulse signal with high precision.
SOLUTION: In this method, a pulse signal is constituted so as to be involved in a time window. A control signal which contains an identification showing the position of a pulse in a corresponding window, in connection with each pulse is provided for a pulse generator. Further, continuous groups of N bits which coordinately define a digital sign showing the position of a pulse inside the window are transmitted by transmission frequency (Fe) which is greater than a pulse repetition frequency, regarding the respective time windows. The digital position sign is converted to the control signal which is spread in time along the length of the window and contains the position identification, at a moment corresponding to the digital position sign. As a result, the pulse can be positioned inside the window with a time precision equal to 1/N.Fe.
