Because of the deficiency of fixed kernel in bilinear time-frequency distribution (TFD), i.e. for each mapping, the resulting time-frequency representation is satisfactory only for a limited class of signals, a new adaptive kernel function named the radia
由于双线性时频分布(TFD)中固定核的缺陷,即对于每种映射,所得的时频表示仅对有限类别的信号令人满意,一种名为“radia”的新型自适应核函数……(原句似乎不完整)
