Hello everybody,

I am looking for a convolutional decoder for my ground station. I have found 
the ccsds 27 which does the 1/2 code rate. Unfortunately I would like to have ¾ 
code rate.
I found the cc decoder definition with the FEC extended decoder. In 
documentation, it is written that it cannot operate with another code rate than 

Do I misunderstood something or is there any generic “like” convolutional 
decoder that I can use for my purpose?

Thanks a lot
