WebThe fast Fourier transform (FFT) is a common and efficient method to calculate the discrete Fourier transform (DFT). The FFT core computes the FFT using the 2-parallel radix-22 feedforward algorithm. The FFT core takes in a complex data vector as input and outputs the complex vector in the natural order in the frequency domain. WebI've just ported a radix-4 DIF fft from S. Burrus Fortran code to Java. Actually it lacks several optimization, first of all the table driven twiddle factor (sin and cos factors should be pre-calculated). This should speed the fft a bit more (maybe 50%). I've to hack a bit for that but if someone has the correct answer I'll be very happy and ...
