OFDM benchmarking with UHD

GNU Radio
1

Hi all,

(Ubuntu 1304 gnuradio 3.7)

I want to test OFDM in gr_digital using tx_ofdm.grc and rx_ofdm.grc.
(simultaneously using usrp n200 devices)
Where are UHD source and sink in that flow g.?

Since I do not want to add them myself, I want to see how the original
system works.
Do you know where I can find such a thing?

Hi Nasi,

these Flow Graphs are simulation graphs; there is no hardware
sinks/source in there, obviously.
But you can easily make these flow graphs real hardware transmission
flow graphs.
You see the channel model/throttle block? That’s where reality would
happen. Replace that and everything before with a USRP source (in the
rx flowgraph). In the tx flowgraph, remove the throttle and following
blocks and place a USRP sink there.

Greetings,
Marcus
