New Parameters Relevant to the Definition of Ultra-Wideband Signals and Processes
RÉSUMÉ
This paper is devoted to the problem of difference of the ultra-wideband (UWB) signals from the frequency-modulated (FM) ones. As is shown in paper the traditional technique used for the UWB signal definition can erroneously classify an FM signal, being narrow-banded at every single moment of time, as an UWB signal. The authors suggest a concept of a dynamic fractional bandwidth, based on the analysis of the signal spectral density function of the dynamic (window) Fourier transform. The new criterion, based on the suggested concept, has proven its efficiency in defining FM signals.
