Abstract

A new extrapolation algorithm for band-limited signals is proposed directly based on Fou-rier Transform. The iterative FFT algorithm can provide better extrapolation performance and more ac-curate spectral estimates than other developed algorithms for the band-limited signals with a smooth spec-trum. Since the powerful FFT technique and the convergence accelerating factor are used

the iterative FFT algorithm is more practical in the numerical implementation of the algorithm. The numerical exa-mples have shown that the iterative FFT algorithm is an efficient extrapolation algorithm for the noisy data.
