Joe Taylor 68c942a70e Correct the 47-buffer bailout place. Change bailout times 45->46 and 48->49. 2020-03-12 13:00:42 -04:00
Joe Taylor 6e308f0018 More attempts to diagnose or fix the FT8 "hung decoder" issue. 
On the Fortran side:
 - For the nzhsym=41 activation, bail out if m_ihsym reaches 45
 - For the nzhsym=47 activation, bail out if m_ihsym reaches 48
 - Change the format and content of what's written to fort.71
 - Change msdelay from 10 to 1

In mainwindow.cpp:
 - change format and content of what's written to qDebug
 - always start FT8 decoder at m_ihsym = 41, 47, and 50
 2020-03-12 12:33:34 -04:00
Joe Taylor d69cb49e9a Diagnostic writes to fort.71 in jt9a.f90. 2020-03-11 14:02:19 -04:00
Joe Taylor 199ff3dd3d Experimental work-around for FT8 decoding on slow computers. Important changes: 
- don't start function decode() is decoder is already busy
  - send updated m_ihsym to jt9[.exe] via ss(1,1).  Bill won't like this!
  - jt9 bails out of the 41-buffer pass at m_ihsym=45.

2. mainwindow.cpp: based on the time when <DecodeFinished> is received, calculate
mswait to try to place the killFile time at 0.75*m_TRperiod.

Steven Franke 38bac5e335 Merge branch 'develop' of bitbucket.org:k1jt/wsjtx into develop 2020-02-25 10:56:22 -06:00
Steven Franke 0ca6cbb575 wsprd: improve decoding and reduce the number of false decodes 
Hashtable entries now include the 4-digit grid obtained from the most
recent Fano decode of the callsign. The stored grid is used to validate
OSD decodes. OSD decodes of type 1 messages are accepted only if the
callsign is present in the hashtable and if the grid matches the grid
stored in the hashtable.

Steven Franke 96ad947a37 Implement decode quality metric for FT4. 2020-01-27 09:55:34 -06:00
Steven Franke 70b84478f0 Add WW_DIGI to the special activities section. Make necessary changes to 
the decoders. Also, an experimental change to the FT4 decoder to base
AP decoding passes on 4-symbol block detection instead of single symbol
detection. This provides about 1 dB improvement on the AWGN channel.
Sensitivity changes on other channels are TBD.

Steve Franke a0d471cb0b Improve FT8 SNR estimates in two ways: 
(i) SNR no longer saturates at +20 dB
(ii) a large signal in the passband no longer causes the
SNR of weaker signals to be biased low.
 2019-11-27 15:58:52 -06:00
Steve Franke 091b7f03ed Delete un-needed file. 2019-11-27 15:57:40 -06:00
Steve Franke d1530b0c19 Rename ft8sim files as follows: 
ft8sim_gfsk.f90 => ft8sim.f90
ft8sim.f90 => ft8sim_fsk.f90

This change reflects the fact that the GFSK waveform is now used in WSJT-X
for ft8 and ft4.
