Fractal analysis of The fractal ultra-wideband signals
(2015) Chernogor, L. F.; Lazorenko, O. V.; Onishchenko, A. A.; Karazin, V. N.
The results of fractal analysis of the fractal ultra-wideband (FUWB) signals were proposed. With usage of the continuous wavelet transform the time-frequency structure of that signals was investigated. Calculating the box and the regularization dimensions for each model signal with various its parameters values, three different estimators were applied. The optimal estimations of the fractal dimension value for each FUWB signal model were defined.
System spectral analysis of The fractal ultra-wideband signals
(2015) Chernogor, L. F.; Kravchenko, S. G.; Lazorenko, O. V.; Karazin, V. N.
The theoretical basis and practical peculiarities of the system spectral analysis are briefly considered. The necessity and the expediency of simultaneously application of different linear and non-linear integral transforms during the system spectral analysis performance are explained. The system spectral analysis usage for investigations of the time-frequency structure of the fractal ultra-wideband signals is shown to be effective and useful.
