Fractional Fourier Transform of Rectangular Signals
Fractional Fourier Transform (FRFT) Implementation for Rectangular Signals with Code Modules: wigner_ville_1.m (Single-component signal denoising), wigner_ville_2.m (Dual-component parallel signal denoising), wigner_ville_3.m (Three-component signal frequency detection). The FRFT provides a comprehensive time-frequency representation as the order parameter continuously varies from 0 to 1, transitioning signals from pure time domain to pure frequency domain characteristics.
