【Abstract】 The detection of the quadratic phase coupling has been widely applied in various field such as EEG data analysis,oceanography,sonar and medical biology.In this paper,instead of using the bispectrum to detect the quadratic phase coupling,a new method based on -dimension spectrum is developed.Simulation results show that this methodis much simpler and costs little computer time as well as has high resolution ability.It is sure that this method has much application value.更多还原
