happens in fsk_demod_freq_est
I converted that algorithm to java and played with it. One thing I noticed
though, and I'm not much of a DSP person, was that it is doing a size 1024
FFT with a 1920 samples, so I assume it just ignores the extra samples at
the end.
I'm wondering if a 2048 FFT would be better (more memory though, and wasted
at the end). Maybe downsample the 1024 reals back to 512 reals again.
Maybe not enough to worry about??
Thanks all, interesting stuff!
