Abstract: [cze] [eng]
Tato prace se zabyva problematikou spektralni analyzy ve vysokem rozliseni. V prvni casti prace jsou predstaveny vybrane metody, ktere jsou nasledne na zaklade implementace v programovem prostredi aplikace Matlab porovnany. Zaroven je resena i problematika redukce interferencnich slozek v kvadratickych casove–frekvencnich distribucich. Druha cast prace se venuje implementaci a optimalizaci algoritmu pro vypocet vyhlazene Wignerovy distribucni funkce v realnem case. This thesis deals with the topic of high resolution spectral analysis. In the first part, selected methods are presented and afterwards compared based on the Matlab implementations. The problematics of reduction of crossterms in quadratic time–frequency distributions is also covered. The second part is focused on the implementation and optimization of the algorithm for real-time computation of smoothed Wigner distribution function.
Keywords: quadratic time–frequency distributions; spectral analysis; Wigner distribution function; ZoomFFT; kvadraticke casove–frekvencni distribuce; spektralni analyza; Wignerova distribucni funkce; ZoomFFT
