Abstract: A device and a method are presented for generating an intermitted oscillating signal comprising a plurality of oscillating portions separated from each other in time. The device and method are suited for communication systems, in particular for Ultra-Wide Bandwidth (UWB) applications. The device comprises a variable oscillator for generating the oscillating portions; switching circuitry for switching on/switching off the variable oscillator at the beginning/end of each oscillating portion; and circuitry for setting initial conditions in the variable oscillator to impose a predefined transient and a characterizing frequency upon each start-up.

Abstract: A method for generating an ultra-wideband communications signal is described. The method includes generating a piecewise linear ultra-wideband baseband signal comprising at least one pulse, based on an inputted data signal; generating a carrier tone having a carrier frequency suitable for wireless transmission; and upconverting the baseband signal with the carrier tone to the carrier frequency. A method for interpreting a received ultra-wideband communications signal, the signal having a center frequency in the RF domain, is also described. The method includes generating at least one local signal template, synchronized with the received ultra-wideband communications signal and having substantially the same center frequency; correlating the received ultra-wideband communications signal with each of the local signal templates in the analog domain, obtaining at least one ultra-wideband baseband signal; and interpreting the at least one ultra-wideband baseband signal to generate a data signal. Devices for implementing these methods are also described.

Abstract: An analog to digital converting device is proposed for generating a digital output signal of an RF analog input signal. The device comprises a first analog to digital converter stage, a mixer, a second analog to digital converter stage and a digital filter. The first analog to digital converter stage generates a first and a second output signal. The first output signal is inputted in the filtering means. The second output signal is being down-converted to a signal with an intermediate frequency or DC. Thereafter, this down-converted signal is being fed to the second analog to digital converter stage. The digital output signal of this second stage is further processed together with the first digital output signal in the digital filter to a digital signal representative of the analog input signal.
