Comparison Between Radix-2 and Mixed Radix FFT
Article Abstract: The basic theory and algorithm of radix-2 and mixed radix FFT are presented in the paper.The performance of the two algorithms is compared and analyzed through the simulated data.The result shows that the speed of radix-2 algorithm is faster than mixed radix algorithm,and the effect of spectrum of mixed radix FFT is better when the points are truncated with the integer period.
