摘要
通过离散Fourier变换,给出了一个频域极小化外推算法。该算法能较好地抑制噪声干扰,其计算量小,计算机仿真结果表明,该方法有良好的应用前景。
In this paper, a digital method of superresolution of high - frequency reconstruction is described through Fourier transform. This method can deal with noise interference more effctively and its computational complexity is also lower. The computer simulation results show that this method enjoys a much brighter applicable prospect.
