摘要
本文给出能量有限带限信号外推问题新的解析解,它比长球波函数展开法更为简单。基于新的解析解公式,给出了相应的算法和稳定性判据。
This paper proposes a novel method to obtain a simple analytical solution to extrapolation problem for band-limited signals, which is much easier than prolate spherical wave function expansion method. The corresponding algorithm for extrapolation is built with a criterion of rubustness.
