摘要
FFT是数字信号处理中最重要的算法,在研究了实序列的FFT的特点之后,推导了两种高效的实序列的FFT的算法,并将其应用于相关函数的测量,使其分析速度得到显著提高。
Fast Fourier Transform(FFT) is the most important algorithm in Digital Signal Processing.This paper studies the characteristic of FFT of Real-Sequence,derives two FFT algorithm of Real-Sequence,and then applies it to the measures of correlation-function.The pace of analysis is notably increasel.
