I was thinking some more about Jame's talk on Wolf yesterday,
and I have a few basic questions.
Wolf consists of a data encoding system layered over an
error recover system, layered over a bit synchronisation system
finally layered over bpsk. The upper layers woud work fine
over any transmission layer ie dfcw. Is BPSK actually the most
optimal bit transmission system?
Am I correct in thinking that BPSK is so good because you are
actually repeating the bit on every carrier cycle and integrating
I was also thinking that you could send wolf on the divide down
CW transmitters that some folks use. By injecting the audio
tone from a PC into a 13.6MHz transciever operating SSB and
then dividing down by 100 you should generate an equivelent
signal to the linear translation approach save for the envelope
shaping. However by keying the carrier off-on during the transition
the normal CW wave shaping should clean up the signal.
Does this work? Note that the error in the carrier will be the
dominant term, and not the error in the the modulation, which may
have some advantages.
