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.

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.

executing.

c26d0b4f29 FT4: Imrovements to sync. 
Divide DT search range into 3 segments. Search central segment (near DT=0)
first and try to decode the largest peak. Then find the largest peak in each
of the surrounding segments and try to decode those only if the peak is larger
than the one found in the central segment.

Also re-indent ft4_decode.f90 and some other minor tweaks.
