自适应冗余第二代小波在信号去噪中的应用

摘要

The concept of second generation wavelet based on lifting method and the construction method of adaptive redundancy second generation wavelet were described.The adaptive redundancy second generation wavelet and the redundancy second generation wavelet were applied to the analysis of vibration signal denoising of the mine hoist.Test showed that the adaptive redundancy second generation wavelet was more efficient on signal denoising than the redundancy second generation wavelet.%介绍了基于提升方法的第二代小波原理以及自适应冗余第二代小波的构造方法。将自适应冗余第二代小波和冗余第二代小波变换应用于提升机振动信号的去噪分析并进行比较。试验表明,相对于冗余第二代小波,自适应冗余第二代小波在信号去噪方面具有更好的特性。
