Firstly, a TF region extraction method based on energy threshold is designed to identify the clustered energy of the signaland to extract the regions in TF plane occupied by clustered energy; Secondly, linear TF filters are designed to extract thecomp.
首先,设计了一种基于能量阈值的时频区域提取方法,识别出信号在时频面上的能量峰,并提取出能量峰所占据的时频区域;利用线性时频滤波器获取信号中的分量,将这些分量的时频分布叠加得到改善的时频分布。
