I hope you or someone can provide an answer to me on why this is
happening. It is happening with version v2.6.1
Hi Joe,
Thanks for those results. Yes, SF behaves well on those
conditions and FT8 may be close to the edge that is
obvious in the HM model. I was eager to see whether the
10 ms Doppler spread starts to affect to the high SNR
performance, it may or may not. It's not an important
information, just
Hi Reino,
We could do simulations for the "High-latitude Moderate" (HM) channel,
of course, but have not done do. We do know that FT8 does not do very
well under such conditions (Doppler spread = 10 Hz, Differential delay 3
ms): see Figure 7 and Table 6 of our QEX paper on FT4 and FT8, here:
Joe,
Thank you about the excellent document. It does clarify
where we are at the fight against noise and signal
spreading.
I am interested to see also results for the
"High-latitude Moderate" propagation model for SF. FT8
have a lot of difficulties on that kind path as
presented in Figure 7 of T
