| 摘 要： | 介绍了小波变换的多分辨分析理论及其在消噪方而的应用.通过分析可知,小波多分辨率分析能够将信号在不同的尺度上展开,具有对信号按频带进行处理的能力.在信号小波分解后,抽取有关频带进行重建,以达到降低噪声、提高信噪比的目的.文中给出了信号多分辨率分析在信号消噪方面的具体应用实例.

| Abstract: | he multi-resolutions analysis theory of wavelet transformation and its application in noise elimination is introduced here. Through the analysis, the signal can be developed in different scale and processed at different frequency. After being decomposed by the wavelet, the signal at tbe related frequency band is abstracted and rebuilt, so as to decrease or eliminated the noise and the S/N is improved. The detailed examples are given in the paper. |
