Here we have several test programs for use with the gr-trellis implementation.
Documentation can be found in
http://gnuradio.utah.edu/svn/gnuradio/trunk/gr-trellis/doc/gr-trellis.html
fsm_utils.py contains several useful functions.
fsm_files is a directory with some FSM definitions
If you just want to see what these programs do, run each of the following:
./test_tcm.py fsm_files/awgn1o2_4.fsm 10.0 1000
./test_tcm1.py fsm_files/awgn1o2_4.fsm 10.0 1000
./test_tcm_combined.py fsm_files/awgn1o2_4.fsm 10.0 1000
./test_tcm_parallel.py fsm_files/awgn1o2_4.fsm 10.0 1000
./test_sccc_hard.py fsm_files/awgn1o2_4.fsm fsm_files/awgn1o2_4.fsm 10.0 1000
In your terminal you will see something like this:
[anastas@ernesto channel-coding]$ ./test_tcm.py fsm_files/awgn1o2_4.fsm 6.0 1000

1.102539e-03 is the error rate estimates by sending 1000 packets of
1024x16 bits each using an 1/2 4-state convolutional code and QPSK
modulation through an AWGN with Es/N0 = 6.0 dB
