数据科学：维格纳准概率分布（Wigner-Ville Distribution，WVD）
The Wigner distribution, often also Wigner-Ville distribution, is a time-frequency distribution, like the spectrogram, with very interesting properties and a high resolution in both the time and frequency domains. It has the benefits of ideal resolution properties [1] but it also includes signal-dependent interference terms [1] which are mathematical attributes but do not represent pure signal terms.
