This method is different from the filtering approach which may be simple to generate UWB signals but lacks the capability of precisely shape and position UWB signal energy in the frequency spectrum. In our approach, we feed a Gaussian pulse into an analog microwave differentiator array, then, the outputs are combined by a suitably designed power combiner after appropriate signal amplifications and/or attenuations. Because the n-th order derivative of a Gaussian pulse will move the energy concentration part to higher frequency band as n increases, we use this property to design the desired pulse whose energy is distributed at the desired frequency band to meet some specific regularity in UWB applications. © 2006 IEEE. |
