Time-Frequency Signal Analysis and Processing

Sažetak
The instantaneous frequency (IF) of a signal is a component-specific feature ; therefore, its estimation is preceded or accompanied by component separation and extraction. This section considers nonstationary multicomponent signals, and the problem of estimating the IFs corresponding to the individual components using a blind source separation (BSS) algorithm whose aim is to recover unobserved signal components from their observed mixture. The main advantage of this BSS method for component extraction combined by the short-term Rényi entropy (STRE) is its double-directional component tracking capability. Furthermore, proposed algorithm does not require any noise reduction thresholding and it is applicable to signals having components with overlapping time supports.
