Abstract：STFT, WT, WVD and Cohen’s class are the useful tools of signal processing. This paper analyzes the bilinear TF based on WT, and the relation between the scalogram, VWS and Cohen’s class, Furthermore, the scalogram is classified into Cohen’s class, and then WT is generalized to TF domain(scalogram)，ambiguity domain(wavelet AF) and frequency/frequency delay domain(WSCF). The WSCF characteristics of mono-frequency, dual-frequency, WGN, and fractal stochastic noise are analyzed. Finally, a dense algorithm of discrete WT is introduced to the computation of generalized TF distribution based on WT.
