[Discuss-gnuradio] Re: [USRP-users] UHD Announcement - December 13th 2010 - MIMO cable support

[Arun Pillai]

Is the FPGA code for mimo cable support available? Is that also on the 
packet_router branch (you mention only the host code below)? If not, how 
can I access it?

Also, are there example host programs that exercise this code?

Thanks,
Arun
