摘要
介绍了基于提升法的第2代小波原理和自适应冗余第2代小波的构造方法。比较了将自适应冗余第2代小波和冗余第2代小波变换应用于通风机振动信号的消噪分析时的异同。实验得出,相对于冗余第2代小波,自适应冗余第2代小波在信号消噪方面特性更好。
Principles of second generation wavelet based on lifting method and adaptive redundant second generation wavelet constructor. Compare adaptive noise analysis redundant second-generation wavelet and redundancy of second generation wavelet transform for fan vibration signal elimination. Experiment shows, Relative to redundant second generation wavelet, adaptive redundancy of the second generation wavelet features better in terms of signal denoising.
