| 摘 要： | 通过对原数据序列抽取子序列并重新排列得到新的数据序列,在保持数据点数不变的情况下,使采样时间间隔变大,从而FFT变换后的频谱得到了细化。给出了仿真算例,讨论了细化倍数应满足的条件和该方法的适用场合。

| Abstract: | The original data sequence was extracted to several subsequences, and then the subsequences were rearranged to a new sequence. By the method, the sampling interval had been widened and its frequency spectrum resolution was increased. The simulation was given in this paper. And at last, the application of the method, and the choice of the parameters were discussed. |
