Noniterative and fast iterative methods for interpolation and extrapolation
Paulo J. S. G. Ferreira · IEEE Transactions on Signal Processing · 1994
In this correspondence we study the band-limited interpolation and extrapolation problems for finite-dimensional signals. We show that these problems can be easily reduced to the solution of a set of linear equations with a real symmetric positive-definite matrix S with spectral radius /spl rho/(S)>
