Band-Limited Function Extrapolation in Operator Space

Chen Zong-zhi, Kong Fan-nian, Shi Yan-tao (Institute of Electronics, Academia Sinica, Beijing).  
The band-limited function extrapolation can be considered as an approximation problem in operator space, and the Papoulis-Gerchberg method correspones to the case of approximation using Taylor series. A new iterative extrapolation algorithm, based on Lanczos-r approximation, is proposed. Theoretical and numerical analysis show that the new method has a much faster convergence rate than the Papoulis-Gerchberg method.
