- 局部放电试验所采集的信号中往往混有白噪声、周期干扰信号去除。此处采用常用db系列小波中的db6小波进行9尺度的多分辨分解后,根据白噪声能量特性,估算各尺度的阈值大小,采用硬值进行处理,后进行重构。
Single-wavelet-reconstruction
- 小波多层分解单层重构程序,对非平稳时间序列进行多尺度分解,然后进行单层重构。-Wavelet decomposition multilayer single reconstruction program, for non-stationary time series multiscale decomposition, and then single-remodeling.
小波分解与重构
- 对信号进行多尺度分解并提取小波的高频系数和低频系数(Multi-scale decomposition of signals and extraction of high frequency coefficients and low frequency coefficients of wavelet)
