对基2FFT算法计算序列频谱的讨论

An Analysis for Determining a sequence Frequency spectrum using the Radix-2FFT Algorithm

在序列的DFT中,对于非2的整次幂序列常用补零成为2的整次幂,以便采用基2FFT运算程序计算出它的频谱。本文说明了这种方法对序列DFT值的影响,并提出了解决这个问题的方法。

This paper puts forward and deals with a principle and method to calculate sequence frequency of any length with The Radix-2FFT Algorithm, The method is much superior than others in its practical use.
