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/m-block-%3C--%3E-GR-block-integration-t4536641.html 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. Sanmi |
