周期图法谱估计需要对信号序列“截断”或加窗处理
- 周期图法谱估计需要对信号序列“截断”或加窗处理,其结果是使估计功率谱密度为信号序列真实谱和窗谱的卷积,导致误差的产生。本程序分别设计了周期图法,最大熵功率谱估计和Welch法以及它们的对比,最大熵功率谱估计目的是最大限度地保留截断后丢失的“窗口”以外信号的信息,使估计谱的熵最大。-Periodogram spectrum estimation signal sequence needs to " cut off" or add the window handle, the

- 对重分配小波尺度谱存在着时、频分辨率不能同时达到最佳及当振动信号中存在着能量较大的噪声时会降低其时频分布可读性的缺陷,提出一种基于参数优化和奇异值分解(SVD)提高重分配尺度谱时频分布可读性的方法。首先利用Shan— non熵方法优化重分配尺度谱基函数的时间.带宽积(TBP),克服其时、频分辨率不能同时达到最佳的缺陷,再对重分配尺度谱 进行SVD降噪降低噪声干扰影响,提高时频分布的可读性。最后用该方法对仿真信号和滚动轴承故障信号进行了分析,结果表明该方法的时频聚集性更好,抗噪能力更强,能
