摘要
二次相位耦合的识别在EEG数据分析,海洋地理、声纳和生物医学等领域有着广泛的应用。本文在原有利用双谱对二次相位耦合进行分析的基础上,提出了维谱分析方法。模拟实验结果表明,该方法分辨率高,计算方法简单、运算速度快。
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.
