[Discuss-gnuradio] m-block/in-band signaling status/questions

[sanmi]

Hey guys,

 

Our Group currently has a 2x2 MIMO-OFDM system implemented on the USRP/GNU radio platform and we are planning on implementing a 4x4 MIMO-OFDM system which we need working in the next couple of months. We are trying to decide between a custom FPGA solution and the in-band signaling/m-block solution.

 

We saw these recent posts:

http://www.nabble.com/in-band-signaling-project-overview-tf4610363.html#a13166091

 

 

These indicated that the in-band signaling /m-block implementation is almost complete but we are unclear about what is done and what need to be completed. Some specific questions we have are?

 

Status:

1) Is the code in the testing phase or development phase, is there a timeline for completion?

2) Is there a "hello world" example for m-block/in-band signaling?(Simple waveform packet tx/rx with all the functionality)

3) Where can we find the code documentation?

 

Compatibility:

Is the m-bock wrapper for flow graphs (as outlined in the BBN doc) implemented? Specifically, what is the interface between the legacy code and the in-band signaling code? Would we need to redo all our signal processing blocks?

 

Any other comments/suggestions are appreciated.
