Detection of quadratic phase coupling by cross-bicoherence and spectral Granger causality in bifrequencies interactions

Detection of quadratic phase coupling by cross-bicoherence and spectral Granger causality in bifrequencies interactions

Abstract Quadratic Phase Coupling (QPC) serves as an essential statistical instrument for evaluating nonlinear synchronization within multivariate time series data, especially in signal processing and neuroscience fields. This study explores the precision of QPC detection using numerical estimates d...
