And based on the concept of time characteristic scale, a new approach to border processing named extension method based on boundary local characteristic scale is proposed. The approach improves better the impact of boundary effect on EMD.

- 1 對HHT采樣頻率、終止準則、曲線(xiàn)擬合、邊界處理以及模態(tài)混疊等問(wèn)題進(jìn)行了分析,并基于HHT的時(shí)間特征尺度概念,提出了一種新的邊界處理方法:邊界局部特征尺度延拓法,較好地改善了邊界效應對EMD分解的影響。
