Re: [Discuss-gnuradio] 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.
