Uhd_mimo_sink

GNU Radio

Hi all,

I’ve just updated my system and found a problem when trying to use the
uhd_mimo_sink: AtributeError: ‘module’ object has no attribute
‘mimo_sink’.
I don’t know if it has to do with some mistake during the installation
progress and this block is missing or it is something else. Referring to
this I would like to know if someone who has already implemented a mimo
system could tell me which sink/source blocks should be used.I have a
MIMO
cable and I guess the smartest is to use this uhd_mimo_sink and uhd_mimo
source, but it may work too using two simple uhd_usrp_sink and
configuring
one of them as a slave as it is explained in the application notes, is
it
right? I would like to know if someone has experience on that and could
me
to use the best option. Thank you very much in advance! any advice would
be
great!

Those blocks haven’t been present in many releases.

Use the
normal UHD source/sink blocks, and configure the clocking appropriately.
The source/sink blocks can have many, many, many streams, which each
stream connected to different motherboard device addresses, etc.
