On the detection of non-stationary signals in the matched signal transform domain

Andrei Anghel, Gabriel Vasile, Cornel Ioana, Remus Cacoveanu, Silviu Ciochina

ICASSP 2016accepted

This paper proposes a detector of multi-component non-stationary signals based on the matched signal transform (MST). In the MST domain, a non-stationary signal is localized at its frequency modulation rate with the transform's basis modulation function. The MST can be numerically implemented either…

Model-based parameters estimation of non-stationary signals using time warping and a measure of spectral concentration

Andrei Anghel, Gabriel Vasile, Cornel Ioana, Remus Cacoveanu, Silviu Ciochina

ICASSP 2015accepted

This paper proposes a parameters estimation algorithm for signals composed of multiple non-stationary components having the same basis modulation function which is described by an a priori known model and depends on a few unknown parameters. The procedure is based on time warping the signal in turn…
