For multi-component signals,Wigner distribution(WD) is well energy-concentrated but holds cross-terms,while spectrogram,the magnitude-squared STFT,has no cross-terms but bad energy-concentration,thus a time-frequency representation based on geometric mean of WD and Spectrogram(GMWS),which is simple and easy to be realized,was introduced to integrate both advantages.
