功率频谱 meaning in Chinese
power frequency spectrum
power spectrum
Examples
- Based on the existing spectral independent component analysis ( spectral ica ) and non - negative constrained decomposition , a moving time window is introduced , and multiple dominant spectral components are extracted within the short - time window
结合已有的频域独立成分分析方法以及带约束的非负分解处理，引入时间滑动窗口，在短时窗内动态提取多重主导功率频谱。
