decode program, output information, Es/N0

ea4gmz opened this issue · comments

Hello,
When I run decode I obtain this output:
symbol pos: 2298
coarse cfo: 1800 Hz
oper mode: 16
call sign: EA4GMZ
demod .... done
coarse sfo: -0.243791 ppm
finer cfo: 1800 Hz
Es/N0 (dB): 29.2713 29.4451 30.2119 30.7631
bit flips: 0
(which I found is sent to stderr and can be captured with 2> instead of >)
This information is great. I would just like to know what the four Es/N0 numbers mean. Are they related to four different parts of the packet or four different ways of estimating Es/N0?
regards

They are the estimated SNR numbers for each OFDM symbol

Thanks a lot.
