Some questions about radix-4 FFT algorithm using fixed-point arithmetic Hello all, I'm very new to signal processing and want to learn to implement some basic FFT algorithms in hardware. First, I coded up the radix-4 Cooley- Tukey FFT algorithm in Matlab and it is working fine (compared it against the Matlab's builtin FFT) when I use floating point number to represent my signal. ... 8 Feb 2010 21:21
