A cross-terms geometry based method for components instantaneous frequency estimation using the Cross Wigner-Ville distribution
Malnar D.; Sucic V.; Boashash B. (2012 , Conference Paper)A novel method for the signal components instantaneous frequency (IF) estimation based on the CrossWigner-Ville distribution (XWVD) is presented. The cross-terms in the XWVD are deliberately formed between the analyzed ... -
An efficient algorithm for instantaneous frequency estimation of nonstationary multicomponent signals in low SNR
Sucic V.; Lerga J.; Boashash B. (2011 , Article)A method for components instantaneous frequency (IF) estimation of multicomponent signals in low signal-to-noise ratio (SNR) is proposed. The method combines a new proposed modification of a blind source separation (BSS) ... -
A comparison of quadratic TFDs for entropy based detection of components time supports in multicomponent nonstationary signal mixtures
Saulig, N.; Sucic, V.; Boashash, B.; Sersic, D. ( IEEE , 2013 , Conference Paper)Separation of different signal components, produced by one or more sources, is a problem encountered in many signal processing applications. This paper proposes a fully automatic undetermined blind source separation method, ... -
An improved method for nonstationary signals components extraction based on the ICI rule
Lerga, J; Sucic, V; Boashash, B ( IEEE , 2011 , Conference Paper)This paper proposes an improved adaptive algorithm for components localization and extraction from a noisy multicomponent signal time-frequency distribution (TFD). The algorithm, based on the intersection of confidence ... -
Instantaneous frequency estimation and localization
El-Jaroudi, A.; Emresoy, M.K.; Stanković, L.J.; Hussain, Z.M.; Boashash, B.; O'Shea, P.J.; Barkat, B.; Sucic, V.; Lerga, J.; Rankine, L.J.; Djurović, I.; Simeunović, M.; Djukanović, S.; Ristic, B.... more authors ... less authors ( Elsevier Inc. , 2016 , Book chapter)In many applications, a critical feature of a non-stationary signal is provided by its instantaneous frequency (IF), which accounts for the signal spectral variations as a function of time. This chapter presents methods ... -
Measures, performance assessment, and enhancement of TFDs
Boashash, B.; Touati, S.; Auger, F.; Flandrin, P.; Chassande-Mottin, E.; Stanković, L.J.; Sucic, V.; Khan N.; Sejdić, E.; Sucic, V.; Saulig, N.; Shafi, I.; Ahmad, J.; Shah, S.I.... more authors ... less authors ( Elsevier Inc. , 2016 , Book chapter)This chapter describes a number of time-frequency (t,f) performance quality measures specifically developed as criteria for performance enhancement for a given application. The adopted performance measures are defined using ... -
Multicomponent noisy signal adaptive instantaneous frequency estimation using components time support information
Sucic V.; Lerga J.; Boashash B. ( Institution of Engineering and Technology , 2014 , Article)This study proposes an adaptive method for components instantaneous frequency (IF) estimation of noisy non-stationary multicomponent signals, combined with the components time-support estimation method based on the shorttime ... -
Signal content estimation based on the short-term time-frequency Rényi entropy of the S-method time-frequency distribution
Saulig, N.; Sucic, V.; Stanković, S.; Orović, I.; Boashash, B. (2012 , Conference Paper)A key characteristic of a nonstationary signal, when analyzed in the time-frequency domain, is the signal complexity, quantified as the number of components in the signal. This paper describes a method for the estimation ...
