Ultrawideband Signals and Wigner Transform

The Wigner transform well known as the square time-frequency transform from Cohen class for the ultrawideband signal analysis was proposed. The general properties, advantages and disadvantages of the Wigner transform were discussed. Some analytical results of the Wigner transform spectral density calculations for the model ultrawideband signals were shown. That models and the ultrawideband signal models based on the atomic functions were analyzed numerically with the Wigner transform and were discussed. The results of the ultrawideband signal analysis performed the Wigner transform usage with ones based on the short-time Fourier transform were compared
