Re: [Discuss-gnuradio] In-band Signaling (Tickets #121 and #122)

[George Nychis]

Hey Brian,

This is actually in discussion right now :)

Myself and another student are working with the platform with the long 
term goal of developing fine grained MAC protocols, however we need the 
functionality of the m-block and the tighter timing.

Therefore we've started our research project with getting in-band 
signaling on GNU Radio and the USRP, as Eric is already finishing up the 
m-block.  We've been talking with Eric off-list about what needs to be 
modified, the structures, and the approach.

Check out the message from Eric posted to the list on 02/04/07 with the 
subject "USRP in-band signaling."  It gives a brief overview of what 
needs modified.  We're waiting on Eric and Matt to lay out how they want 
things done and their suggestions on approach, then we were going to 
hammer it out.

We would *love* someone with your experience working on it with us, as 
Thibaud has ~a years experience with VHDL and I have no experience with 
it.  Therefore we were going to break it down with Thibaud working 
closely on the Verilog and I would be working more closely with the GNU 
Radio end.

Our major interest is building the MAC protocols, so we were going to 
try and blast through this as fast as possible and with your help and 
experience in working with us that may be more realistic :D  We haven't 
done more than played with the USRP and have been reading documentation 
and code to understand the interaction of the devices.  So, you caught 
us at the very start of this which is great.

- George
