The iterative FFT algorithm can provide better extrapolation performance and more ac-curate spectral estimates than other developed algorithms for the band-limitedsignals with a smooth spectrum.
它在外推性能和谱估值方面比以往的方法好。由于采用了FFT和收敛加速因子,它是一种实用的算法。

This paper proposes a novel method to obtain a simple analytical solution to extrapolation problem for band-limitedsignals, which is much easier than prolate spherical wave function expansion method.
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。

Most of the wireless communication systems are required to achieve least adjacent channel emissions and high bandwidth efficiency, that is to say signals must be transmitted in a limitedband.
