MATLAB信号处理EEMD工具箱
EEMD是针对EMD方法的不足，提出了一种噪声辅助数据分析方法。EEMD分解原理为：当附加的白噪声均匀分布在整个时频空间时，该时频空间就由滤波器组分割成的不同尺度成分组成。当信号加上均匀分布的白噪声背景时，不同尺度的信号区域将自动映射到与背景白噪声相关的适当尺度上去。当然，每个独立的测试都可能会产生非常嘈杂的结果，这是因为每个附加噪声的成分都包括了信号和附加的白噪声。既然在每个独立的测试中噪声是不同的，当使用足够测试的全体均值时，噪声将会被消除。全体的均值最后将会被认为是真正的结果，随着越来越多的测试，附加的噪声被消除了，唯一持久稳固的部分是信号本身。

MOTIVATIONPropeller related acoustic signatures typically exhibit modulationcharacteristics. These modulation characteristics originate from the cavitationprocess that takes place in the water due to the cyclic movement of the propellerThe cavitation process is basically the collapse of air and vapor bubblesdue to variations in the static pressure. These variations in static pressure are aconsequence of the passage of the propeller blades through the water. Thismovement, cyclic in nature, causes amplitude modulation in the static pressureand as a consequence an amplitude-modulated(AM) signal can be detected in areceiverCyclostationary processing techniques have been used to detect andlentify analog and digital communication signals very successfully. Thesetechniques have the advantage of using a more realistic model for the signalthan the stationary model used in most of the more conventional signalprocessing techniquesB BACKGROUNDThe basic elements of cyclic spectral analysis are the time-variant cyclicperiodogram and the time-variant cyclic correlogram. These two functions form aFourier transform pair. This fact is known as the cyclic Wiener relation or thecyclic Wiener-Khinchin relation [Ref. 1: p. 49.1
