On the Gerchberg–Papoulis Algorithm

Jorge L.C. Sanz, Thomas S. Huang

Research output: Contribution to journalArticlepeer-review


In this paper, iterative procedures for band-limited signal extrapolation are considered. Specifically, we will show that the well-known Gerchberg-Papoulis algorithm [1], [2]: gn = sincΩ *(g + (I — T)gn_1), can be considered a special case of an iterative procedure given by Landweber in 1951 [3].
