一个新的带限信号高频重建正则外推算法(Ⅲ)

Regularized Extrapolation Algorithm for a New Band-limited Signal High-frequency Reconstruction(Ⅲ)

本文在[1，2]的基础上，通过离散Fourier变换，给出了一个高频重建正则外推算法。该算法能够较好地抑制噪音干扰。其计算量和存储量较小，给出了一个计算正则参数的新方法，证明了算法的收敛性，计算机实验结果表明，该方法有良好的应用前景。

In this paper, a digital method of superesolution or hig -fequency reeonstruction is described. This method the computational complexity is also lower after proving the convergence of the regularization algorithm,some results of computer experiment are presented.
