I am going more deeply into the OFDM example, however I cannot figure out
which is the bit rate of the usrp.
I mean, I know and I can set the bit rate of my application but how fast the

How can I evaluate the throughput on the wireless link?

Thanks. In addition, check out the messages Morgan Redfield just posted,
he found that the transmit_path multiplier should

Hi Vanessa,
One thing you might also have to change is the tx-amplitude in
transmit_path.py.
Thank you!
I found 2 errors in benchmark_ofdm_tx.py:
line 63 should be "sink"
line 69 should be "samp_rate"
Thanks again

I just pushed a branch with UHD versions of the OFDM apps:
git://github.com/bistromath/gnuradio.git
It's in the uhd_ofdm branch. This is untested code, so use at yo
Yes, but they do not work with UHD which is the only way to use my USRP N210

However we are trying to transmit a packet from a usrp n210 to another usrp
n210 and we are searching for examples do to this simple operation.
How is it possible that are not out there? Do you know any source of simple
examples?
Thanks

Dear Tom,
Do you mind sharing your code for usrp n210 ?
I am new on gnuradio and usrp and I am not able to find a python example to
perform packet transmission.
Thank you

I was under the impression that performance meant high cpu load, too

Hi,
Thanks for the suggestions.
I use two USRP2s. When the receiver is loaded with the UHD driver it
exhibits poor performance. No matter if the sender is using the
standard or the UHD driver.
The buffer shouldn't be the problem:
"Current recv sock buff size: 5000 bytes"
I do get that filte

Hi,
I updated the OFDM example. You can find it at
http://www.cs.ucsb.edu/~veljko/downloads/ofdm_example.tar.gz
It supports both USRPs and the UHD driver. I get pretty bad
performance with UHD receiver for some reason. Any ideas?
Cheers,

Hi,
I was looking for the source codes through the list.
And I got one from Veljko from UCSB, who are very nice to share his codes,
"ofdm_example.tar.gz"
The codes are attached.
Given the enough gain in TX and RX, you can see the output result at RX.

Hi all,
Does anyone know of any updated OFDM benchmark code that is modified to
be run on a USRP2? I have seen previous posts of this, however the
link to the updated code is no longer available.
