Influence of phase noise on coupling diagnostics by the method of phase dynamics modelling using time series of the mathematical model of cardiovascular system
We study the effect of noise on the properties of the directional coupling estimation with the method of phase dynamics modeling. We carry out the analysis on time series of the previously proposed mathematical model of the human cardiovascular system. Directed coupling estimations are analyzed via instantaneous phases modelling of the 0.1 Hz oscillations in heart rate variability and photoplethysmogram, reflecting the activity of the subsystems regulating blood circulation, at various levels of phase noise. The results of the analysis of the model signals are compared with the results of the analysis of experimental signals.
