k9an b3d15ea0c6 Prevent a divide-by-0 error in ftrsd2.c. 2021-04-26 08:08:27 -05:00
Steven Franke e90cc846bb Implement AP decoding for JT65 (VHF/UHF/Microwave only). 
git-svn-id: svn+ssh://svn.code.sf.net/p/wsjt/wsjt/branches/wsjtx@8277 ab8295b8-cf94-4d9e-aec4-7959e3be5d79
 2017-12-02 16:04:51 +00:00
Steven Franke e25dd201a3 Experimental changes to JT65 decoder: 
1. Change to rectangular FFT window for 2D sync spectrum (ss).
2. Move 2D sync spectrum array to common block.
3. Change to quarter-symbol steps for the ss array.
4. Allow up to 4 decoding passes.
5. Wire up Fast/Normal/Deep for 2, 3, or 4 decoding passes.
6. Make minsmo=0 (instead of 1) for minimally spread JT65B/C signals.

the whole passband.
