A new approach for estimation of obstructive sleep apnea syndrome

► OSA patients were differentiated from normals using EEG signal. ► QPC in δ, θ, α, β and γ subbands of EEG were obtained by bispectrum analysis. ► The Quadratic Phase Couplings were quantified and coupled to a NN classifier. ► This technic has provided OSA detection with 96.15% accuracy.
