Dear Sylvain
In code provided above there is no
*conv_tch_afs_XX_XX_next_term_state* &*
conv_tch_afs_10_2_next_term_state*struct for some of bitrate so its
giving wrong output for convolution
decode.
is it possible to give complete conv_tch_afs.c decode.

search some
materials, find that the decode method of AFS convolutional
code is different from the EFS`, it use RSC, and need SOVA(soft output
viterbi algorithm). am i right?
No.
It _does_ use RSC (and the viterbi code in libosmocore supports RSC).
But that has nothing to do with SOVA and SOVA is _not_ required at
all.
AFAIK, the AMR code I sent a while is correct. Just to be sure I
attached the latest version I have. I haven't tested all the modes but
at least 12.2 and 10.2 should be correct.
Cheers,
Sylvain
