+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:

modulated. Since we are simulating the communication system, we need not
simulate the actual waveforms. An M-ary, N-dimensional
modulation is completely specified by a set of M, N-dimensional real vectors.
