I'm having to use long lists. Not good with short messages, the outer code isn't strong enough and there are lots of false decodes. EbNaut would fail if Joe was sending a random payload because we wouldn't know which was correct. The operator here is adding a 3rd layer to the FEC. I might alter the coding on short messages. Instead of extending the CRC (which would invalidate previously recorded signals) I would restrict the source coding to say A-Z 0-9 and maybe /. Enough for a callsiga or a small cat. That would add 0.5 bits per char of strength to the outer code, 21:00 at offset T=+1.0 found rank 1360: VO1NA ps [ 33 120 120 150 150] re-encode 176/512 ber 3.44e-01 Es/N0=-10.9 Eb/N0=1.4 Andy wrote: > How can I make a copy of the text in the EbNaut window ? > Highlight and copy (Windows) doesn't work I don't know how to do the copy/paste stuff in Windows. You're probably better off looking in the log file, this will list all the decodes. A good but false decode will over-write the screen display of a not-so-good but correct decode, but the original is in the log. -- Paul Nicholson --
