| file | mmwavelib_fft16pt.c |
| | Routine to compute 16pt FFT of a vector of length 8 (assumed to be zero-padded to length 16)

| file | mmwavelib_ffttwiddle_gen.c |
| | Contains functions related to generate FFT twiddle factors. The functions are optimized for speed to allow quick reconfiguration when switching sub-frames in advanced frame mode. For FFT size less than or equal to 1024, the implementation is to store look-up table which is very high in memory consumption. For FFT size 2048, 4096, and 8192, the implementation is to use trigonometry formulas for interpolation from the look-up table.

| | Contains functions related to generate windowing coefficients for FFT processing.
|
| |
| file | mmwavelib_windowing.c |
| | Contains functions related to windowing of data (typically prior to an FFT)
|
