本文提出采用希尔波特-黄变换（HHT）方法从干扰和噪声中提取微弱的冲击无线电信号。
The Hilbert-Huang Transform(HHT) methods is used to extract the weak impulse radio signal from interferential and noisy environment in this paper.
将希尔伯特黄变换应用于水声矢量信号处理之中，提出了矢量希尔伯特黄变换法(矢量hht)。
An application of Hilbert-Huang Transform in underwater acoustic vector signal processing was introduced and a new method of vector Hilbert-Huang Transform (vector HHT) was developed.
为了体现这一特点，本文将HHT进一步称为希尔·波特-黄变换局瞬信号分析(HHT - LISA)。
For showing this characteristic, this paper further calls the HHT as the Hilbert-Huang transform Local-instantaneous signal analysis (HHT-LISA).
介绍了希尔伯特黄变换算法的原理及流程，利用由希尔伯特谱反映出的丰富的物理信息来对齿轮进行故障诊断。
This paper explains the theory and algorithm of the HHT. It employs the plenty of information of gear embodied in Hilbert spectrum for fault diagnosis.
虽然HVD方法和希尔伯特黄变换（HHT）方法这两者均以希尔伯特变换为基础，但HVD方法避免了复杂的经验模式分解（EMD）过程。
The proposed HVD method was based on the Hilbert transform(HT), just as Hilbert-Huang transform(HHT), but did not involve complicated empirical mode decomposition(EMD).
