Wigner Ville Distribution

The Wigner-Ville distribution (WVD) is a time-frequency representation used to analyze non-stationary signals, offering high resolution in both time and frequency domains. Current research focuses on improving WVD computation speed and accuracy, particularly through novel algorithms and architectures like recursive methods for efficient parallel processing and the integration with neural networks for improved signal classification. Applications span diverse fields, including signal processing (e.g., speech and audio analysis, pitch estimation), material science (e.g., characterizing electron gas phases), and physics (e.g., modeling coherent radiation and quantum systems), highlighting its versatility as a powerful analytical tool.
