We are working on using GNURadio for using it as RF node capable of
22/44 MIMO. All the RF nodes are connected to very big FPGA like the
one used in “Berkeley Emulation Engine (BEE)” using “Infiniband”
Optical Fiber. All the signal processing is implemented in “BEE”
hardware. We wanted to replace USB with Infiniband so that we can send
raw ADC/DAC samples to/from BEE processing engine. It would be very
helpful if some body could give us pointers on how to do this so that
we can reuse most of the design of GNUradio board.
Also, I have come across some people using two GNURadio boards for 44
MIMO. Is there a document which describes how to synchronize the LOs
of two GNURadio boards for coherent MIMO processing and program two
GNURadio boards for 44 MIMO??
