A fast Fourier transform (FFT) is any fast algorithm for computing the DFT. The development of FFT algorithms had a tremendous impact on computational aspects of signal processing and applied science. The decimation-in-time (DIT) fast Fourier transform (FFT) very often has advantage over the ...
为了熟悉Radix-4 DIT FFT算法,建议先理解Radix-2 DIT FFT算法。 基本原理 设序列x[n]的长度为N=4M,M为整数。如果不满足这个条件,可以通过补零,使之达到这个要求。我们通过抽取将x[n]分为四个长度为N/4的子序列如下: x1[n]=x[4n] x2[n]=x[4n+1] x3[n]=x[4n+2] x4[n]=x[4n+3] 则x[n]...
在Radix-2 DIT FFT算法中,N点FFT由\log_2 N个阶段组成,每个阶段由N/2点的Radix-2 DIT蝶形结构组成。每个蝶形结构运算需要1次复数乘法和2次复数加法。因此,Radix-2 DIT FFT计算总共需要的复数乘法数量为N/2\log_2N,复数加法的数量为N\log_2 N。如果剔除掉旋转因子W_N^0这种乘法,那所需的乘法次数会更...
This method is not fully optimized, but it is far quicker than using a DFT algorithm on 3000 frequencies. Another very effective variant is called “radix-4” FFT, which requires that the number of points be 4 to a given power (4, 16, 64, 256, etc.). There is also the prime-...
