FFT+FT Continuous Refinement Fourier Transform Analysis Correction Method

According to Professor Ding Kang's "Discrete Spectrum Correction Technology", the FFT+FT Continuous Refinement Fourier Transform Analysis Correction Method employs a novel approach to enhance precision and accuracy in signal processing. This method leverages discrete spectrum correction principles by implementing continuous refinement Fourier transform analysis to further correct and modify data. The technique involves initial FFT processing followed by iterative FT refinements around specific frequency bins, using algorithms like phase-based or amplitude-based correction to minimize spectral leakage and picket fence effects. Implementation typically requires developing functions for interpolation, harmonic identification, and error compensation through weighted averaging or polynomial fitting. This approach significantly improves the reliability and accuracy of spectral analysis results. Your valuable feedback and suggestions on this methodology would be greatly appreciated.
