Abstract :
The authors investigate the extrapolation of a one-dimensional sequence subject to the contraints that its spectrum be bandlimited to a given frequency band and that it be real-valued and nonnegative on that band. A new and easily computable matrix test for the existence of a bandlimited, positive semidefinite extrapolation is derived, and an algorithm is presented for the recursive computation of such an extrapolation
