viterbi / trellis source needed

[abba]

Hi,
I'm searching for 'matlab' (and C!) language Viterbi algorithm implementation.
the both rate are 2/3 and 1/2. i need this for trellis decoding in wlan standard (IEEE802.11b/g).
can anyone help me? many thanks...

for soft input soft output viterbi algorithm serch this forum for "turbo code" i have posed a matlab code there.

Re: mayyan

Hi mayyan,
I have search the "turbo code" in PC Programming and Interfacing forum, but I can not find the soft in and soft out viterbi algorithm. Please tell me the name of the topic on which you have put the program. thanks!

hi

look here for M.C. Valenti work:

http://www.csee.wvu.edu/~mvalenti/

there is a matalb code there. you can also search for his Ph.D which has exelect description of the algorithems.

hope it will help
