tell me to do to
see if it works.Thanks again.

inter,
think of whatever is AFTER the trellis encoder and BEFORE the viterbi
decoder as an equivalent channel.
What is the equivalent channel in your case?
What is its input alphabet? what is its output alphabet?
From your description, it seems that the input alphabet is the same as
the outpu

You probably want to use the trellis_viterbi_combined block.
The documentation for the trellis blocks is in
gnuradio/gr-trellis/doc/gr-trellis.xml.
(if you have xmlto installed then an html file is also built.)

Hi all:
Now I want to use the Trellis_encoder block in the GRC to make an example
for the convolutional code.In my opinion, I use Trellis_encoder to produce the
convolutional code, then make the convolutional code through the modulator and
demodulator(such as DPSK), finally use some bloc
