Hey,
I solved it by my own. After increasing the value of scale_i and scale_q
(e.g. 2) I was able to transmit something.

Hi,

Achilleas,
I have looked at the gr-trellis code and my understanding is that the
code is used mainly for simulation in GNU Radio (signals don't go over
the air). I was thinking about integrating the code into the digital
examples, e.g., transmit_path.py and receiver_path.py. However, I have
Regarding interleaver, this is already implemented in gr-trellis in
a very general (block) form (any kind of permutation of n units of
arbitrary byte length. See interleaver.h/cc and
trellis_permitation.h/cc/i files for details.
Regarding BCH it would be nice to have a gnuradio module

How can I replicate this error? What program/command did you run?

Alex,
Yes, for what I'm doing, the optical link will be AWGN. I'm doing direct
detection (lots of photons) with a uncooled Si photodiode.
Thanks for the feedback. I have limited (none) experience with realtime
receivers so it's hard for me to judge how much loss I'll experience from
