The extrapolation of high-dimensional band-limited functions
Xingwei Zhou, Xiang‐Gen Xia · IEEE Transactions on Acoustics Speech and Signal Processing · 1989
The Papoulis (1975)-Gerchberg (1974) algorithm for the extrapolation of one-dimensional band-limited signals is extended to multidimensional band-limited signals. Thus, an extrapolation method for these signals is obtained. One- and two-dimensional cases are discussed. A theorem and detailed proof are provided.>
