OK. Your scope explanation might be a good start for discussions on 
this maillist. Some body has to start heating up people freezed 
somewhere inside this list :-)

There must be some way for me to get the access to synthesis tools 
and implement them at campus. I'll try to get one so that I have 
something to do when all my friends go home for christmas.

Wow !! Could you describe more on what kind application is it going 
to be implemented ?

Which part. Who knows I might help.

OK. It does not mean that I have lot of spare time, but I'll try to 
catch up with the assignment you are given then.

APP decoding, never heard of it :-). Turbo code, AFAIK, is surely 
better than convolutional code. LDPC .. the same as for APP decoding.

Just show that we can create something useful, then people will start 
coming by itself I guess.

By the way, for the last 4 months, I've got inquiry from someone in 
India who is trying to implement the Viterbi decoder too. Not sure 
that his project could be shared among the Opencores community, but 
he still have some troubles too, so maybe we just have to wait a 
little longer.
