“Robust Scale/Time-Limited Extrapolation with Denoising”
by Li-Chien Lin and C.-C. Jay Kuo
March 1994
We examine a new signal modeling technique using wavelets, and propose an iterative scale/time-limited extrapolation algorithm. The ill-posedness of the problem is discussed. To obtain a robust extrapolation scheme for handling noisy data, we incorporate the extrapolation algorithm with a denoising procedure which exploits the time-localization property of the wavelet transform. A numerical experiment is given to compare the proposed algorithm with the regularized extrapolation method.
