Better approach for FEC

Hi,

I have a burst system in gnuradio which is working fine with usrps. I
have
used tags (tx_time, tx_eob and tx_sob) to define packet boundaries and
transmission time. Tags are inserted by a block which is connected
before
the usrp sink. I did not use any “tagged stream block” in the burst
system.
All the blocks used are streaming blocks.

Now I want to insert FEC in my system. After going through the FEC API,
I
realized that I can use any of FEC deployments (Streaming, Tagged
stream,
Asynchronus). Are there any difference(s) performance wise? Which one
should is better for my system?

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

Comments are appreciated.
