Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely:  investigate the question of what the joint moments of a signal are by considering the joint moments of the spectrogram for limiting cases of the window. Operator methods are also explored. Expressions for the joint moments are derived, which reveal the distorting effects of the spectrogram window. Knowledge of the joint moments of a signal may be useful in estimating positive time-frequency distributions, or in signal classification of nonstationary signals.

I am writing a research paper on a idea What are the joint time-frequency moments of a signal?
