Abstract

Abstract: A signal decomposition algorithm based on discrete wavelet transform was raised.The results of the experiments show that the proposed method works well in overcoming traditional signal decomposition the worse frequency resolution in the high frequency segment，but the worse time resolution in the low frequency segment.

Key words: Discrete Wavelet Transformation（DWT）, signal decomposition, resolution

摘要： 提出一种基于离散小波变换的信号分解算法.实验结果表明，该算法较好地克服了传统信号分解在高频段的频率分辨率较差，而在低频段的时间分辨率较差的缺点。

关键词: 离散小波变换, 信号分解, 分辨率
