Re: [Discuss-gnuradio] Problem in using trellis Error, correction en- and decoder

[Johannes Demel]

Hey Siva,

in [1] I parameterized the trellis module for a rate 1/3 code as used in 
LTE. Maybe that helps. I put a lot of comments in.
Besides if you tell us what you want to achieve exactly, someone might 
give more specific hints.

happy hacking
Johannes
