资料介绍

This packet contains the C source for a mixed-radix FFT routine. It performs a fast discrete Fourier transform (FFT) of a complex sequence, x, of an arbitrary length, n. The output, y, is also a complex sequence of length n. y[k] = sum(x[m]*exp(-i*2*pi*k*m/n), m=0..(n-1)), k=0,...,(n-1) The largest prime factor of n must be less than or equal to the constant, maxPrimeFactor defined in mixfft.c. The input/output variables are each stored in two arrays comprising the real part and the imaginary part respectively. The routine is accompanied by a demo program, fftbench.c, that demonstrates the numerical capabilities. It measures the execution time as well. If you wish to test the capabilities of another FFT routine, the fftbench.c is easy to modify.
