Abstract :
The possibility of distinguishing of the ultrawideband (UWB) and frequency modulated (FM) signals is considered. It is demonstrated that FM signal, being narrowband in each instant of time, with the traditional UWB signal definition usage can be falsely classified as the UWB signal. The dynamic fractional bandwidth conception based on the analysis of the spectral density function of short-time Fourier transform is proposed. The efficiency of the new criterion based on this conception for FM signal analysis is shown.
