I have attached a picture of my current system and identified where I want
to insert FEC in tx and rx.

Comments are appreciated.

Comments please ?

I think many of the folks who would have comments on this are at the Gnu
Radio conference this week…

Bob,

The various models of handling packets through a GNU Radio system are
dependent on a few things, none of which are easy black/white issues to
describe or offer support on. Partly, it can just be your opinion on
where
the lines are between the different models; or based on what blocks are
available in the different models. You don’t want to go back and forth,
though, so when you move from a stream into a PDU-based system, you’ll
want
to stay there.

Performance is going to be dependent on the rest of your system as well.
We
can’t tell you one is better than the other, but we’ve put in a lot of
hooks into the system to help you understand those issues for yourself,
like using the performance counters and naming each thread with the
block
name so top/htop can help.
