Analysis of local time-frequency entropy features for nonstationary signal components time supports detection
Sucic, Victor; Saulig, Nicoletta; Boashash, Boualem ( Elsevier Inc. , 2014 , Article)Identification of different specific signal components, produced by one or more sources, is a problem encountered in many signal processing applications. This can be done by applying the local time-frequency-based Rényi ... -
An automatic time-frequency procedure for interference suppression by exploiting their geometrical features
Saulig, Nicoletta; Sucic, Victor; Boashash, Boualem ( IEEE , 2011 , Conference Paper)This paper presents an adaptive method for interference suppression in the Wigner-Ville distribution. The structure of the artifacts in the Wigner-Ville distribution has been analyzed to optimally mask the signal Wigner-Ville ... -
Estimating the number of components of a multicomponent nonstationary signal using the short-term time-frequency Rényi entropy
Sucic, Victor; Saulig, Nicoletta; Boashash, Boualem ( Springer , 2011 , Article)The time-frequency Rényi entropy provides a measure of complexity of a nonstationary multicomponent signal in the time-frequency plane. When the complexity of a signal corresponds to the number of its components, then this ...
