- EMD经验模态分解，用来实现信号的分解和分析，是Hilbert的一部分。-EMD empirical mode decomposition for signal decomposition and analysis is part of Hilbert.
EEMD
- 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,唯一持久稳固

333
- 若信号间的能量和频率比例过大，经验模式分解不能分解出正确的单一模式分量。针对这 种状况提出一种经验模式分解与独立分量相结合的信号分析方法。该方法能分离出 IMF 分量的固有特性， 消除EMD分解过后各IMF之间信息混淆问题，恢复各个单分量所丢失的信息特性，改善了经验模式分解能力不足所带来局限性，保障经验模式分解的有效性。-If the signal energy and frequency ratio is too large, the empirical mode decomposit
