are you familiar with OSSIE project (http://ossie.mprg.org) ? It's an
open source SCA implementation and they use USRP as their RF front
end. Perhaps that could be a better place to start. However, I'm not
sure what is your ultimate goal.

I've always thought it would be interesting to encapsulate a gnu radio flow graph inside an SCA component. This would provide a rapid component development environment for SCA waveform developers.

I'm very familiar with the SCA and OSSIE and know enough GNU Radio to be dangerous. I strongly suspect you could create gnu radio blocks to adapt the GNU Radio control and data interfaces to the SCA port structures. I haven't had time to look into this, but I am pretty sure it could be prototyped in a few weeks.

This would be an interesting exercise. At first I saw this as a way to get around the old single threaded nature of GNU Radio, but the thread per block scheduler resolved that issue in a much cleaner way. The rapid prototyping for SCA waveform development is still very interesting.

Basically, SCA and GNU Radio are two different methods to implement SDR.
However, SCA has CORBA as software bus to add different applications. I am
thinking if I can treat GNU Radio as non-CORBA modem applications and plug
GNU Radio into the SCA core framework through a adapter. I think that I need
some guides at this moment to figure out if this direction is possible. If
anyone has comments, please tell me!! Thank you so much for your time and
