What is the difference between FFT and LTE FFT IPs
From the documentation it appears that the Lite FFT is something that meets "requirements of 3GPP LTE standard" which, based on a quick google search, is a mobile communications standard (not sure what that even is) defined by a group of organizations. This appears to affect the transform's "length" which I'm also not sure of the meaning of a transform's length (time, # of bits, # of summing iterations etc).
The FFT appears to just be a regular algorithm for a FFT.
I'm just trying to make a PID controller and I'm not sure which FFT I should use. I just need the fastest/most accurate FFT and possible compatibility with MATLAB (which I see the FFT one does have).
