Hello Frank, Great to see you having a go with the Octave scripts.
I broke the fdmdv Octave simulation while developing the cohpsk modem, as I modified some of the fdmdv.m functions to make them easier to use by the cohpsk code. Use of proper structures rather than globals, stuff like that. So the fdmdv.m Octave code will need some TLC to get it running again. Unfortunately it's not something I have the time to work on right now, many other exciting projects on the boil. However we now have a much better modem which is where the leading edge development is happening - cohpsk. Try tcohpsk.m and see if that runs for you, and let me know how it goes.
