Generalised phase synchrony within multivariate signals: An emerging concept in time-frequency analysis
(2012 , Conference Paper)
This paper introduces the notion of the instantaneous frequency (IF) based generalized phase synchrony in time-frequency analysis based on the concept of cointegration. This phase synchrony is then quantified by investigating ...
A time–frequency based approach for generalized phase synchrony assessment in nonstationary multivariate signals
(
Elsevier
, 2013 , Article)
This paper proposes a new approach to estimate the phase synchrony among nonstationary multivariate signals using the linear relationships between their instantaneous frequency (IF) laws. For cases where nonstationary ...
Detection, classification, and estimation in the (t, f ) domain
(
Elsevier Inc.
, 2016 , Book chapter)
Several studies involving real-life applications have shown that methods for the detection, estimation, and classification of nonstationary signals can be enhanced by utilizing the time-frequency ((t,f)) characteristics ...
Time-frequency methodologies in neurosciences
(
Elsevier Inc.
, 2016 , Book chapter)
This chapter presents a number of time-frequency (t,f) techniques that can provide advanced solutions to several problems in neuro-sciences with focus on the monitoring of brain abnormalities using EEG and other physiological ...
Robust estimation of highly-varying nonlinear instantaneous frequency of monocomponent signals using a lower-order complex-time distribution
(
Elsevier B.V.
, 2013 , Article)
This paper proposes an approach for robust estimation of highly-varying nonlinear instantaneous frequency (IF) in monocomponent nonstationary signals. The proposed method is based on a lower order complex-time distribution ...
