| 摘 要： | 信号重构主要研究如何从观测得到的部分数据来重构原信号。针对原有离散周期信号时域重构公式的缺陷，找到了借助于DFT的内插重构公式，该公式与原有公式相比可在任意时间点重构出原信号，计算结果表明这种内插重构公式重构效果较好。

| Abstract: | The main purpose of signal reconstruction is how to reconstruct signals from observed portion dates. Aimed at the disadvantage of time reconstruction formula of discrete periodic signals, a new formula with the help of Discrete Fourier Transforms (DFT) is obtained. Compared with the time reconstruction formula, this new formula can reconstruct signals at any time.The calculating result shows that the reconstruction effect of this new formula is much better. |
