Abstract
Other work dealt with bandlimited signal interpolation. These studies involved designing a new interpolation algorithm, which is minimax optimal for the interpolation of bandlimited signals. Assuming a class of computationally efficient interpolators, a suboptimal interpolation algorithm was developed and it was shown that the new algorithm outperforms many other interpolators often used in practice. Then, the interpolation problem is formulated as a problem of statistical estimation. This study answers many questions regarding the choice of interpolator and regularization of the algorithm when the original data are noisy.
