Hello,
I have been trying to modify certain parts of the digital_constellation.cc
file, but I am unable to see the changes that I make. I have made changes to
the bpsk section of this file. I am making the d_constellation[0] variable
equal to gr_complex(1,0). I am trying to see my result by print

Hi all,
I would like to be able to remotely terminate a running Python-only flowgraph
(no GRC). I basically set up the XMLRPC server to call "stop()" and "wait()" on
the flowgraph object instance, but it leaves the USRP LO up. I would like the
radio to be torn down completely.

You are using a version of UHD that does not have the functions
necessary to output the USRP configuration. You are either using a
pre-003.004.000 UHD, a recent release, or the maint branch.
This feature is only available on UHD's master branch.

Hi John,
As Marcus already mentioned you can use design functions from firdes module
(gr_filter_design also uses these modules).
Martin, Josh and Tom gave me many suggestions regarding adding the designer to
GRC, so that users can launch the designer from GRC itself (something like this

Yes, I know. Speaking from the standpoint of design flow, it would be
helpful if the user doesn't need to touch those lines of code if they'd
like to take advantage of the filter designer.
For example, if you could output the co-efficients to a file, and your
code calls:
coeffs = get_co

John:
Well, there's already gr.firdes, which can be called
directly from python, and produce coefficients that can be easily
transformed into whatever you need.
Granted, that's only for
relatively-simple filters.
from gnuradio import gr
coeffs=gr.firdes.low_pass(1.0,samp_rate,corner_freq
That is pretty awesome, Sreeraj. Is the output of the program a set of
co-efficients to be copy-pasted, a compilable block, or something else?
It might be useful to have a feature where the user can call a custom
python script with the co-efficients passed as arguments. This would
allow user
Sreeraj -
I just wanted to echo Tom's thoughts that this look really, really great!
I can't wait to see the final version! This will really be a significant
contribution to the capabilities of GNU Radio, in my opinion.
Cheers,

**Amplitude Parameter
Ah. ok! I guess i'll have to look into the variation, I assume it would be
the same for multiple copies of the same USRP model.

Hi,
I am trying to add convolution encoding and decoding to the benchmark
scripts available in gnuradio and test using two N210s. A problem I have
found is that the tailing packets for example last 10 packets out of a
burst of 50 packets are not being received i.e. are not even passing the

Hi guys
I am going through the mimo ofdm code written by Tom Rondeau. In the

antennas also and
accordingly uses the ofdm_alamouti_tx_cc. Can you please let me know if
