Dear Marcus,
Thank you very much for your reply. I had asked you regarding Neural
Network implementation on GNU radio.
I want to explain my problem in detail. Well I am working on Primary user
Emulation Attack in Cognitive Radio. My work includes identifying the
Primary User signal from that of a
Hi all,
Thank you for your replies.

When using messages, simply add a 'time' key to the command dictionary,
and it will be set for the command you're calling. The time stamp value,
is a long/double pair, for full and fractional time. Example:
{'freq': 1e9, 'time': (100, 0.1)}
If this is your message, it will set the frequency to 1
Lefteris,
I would recommend you follow the Guided Tutorials, instead of this page.
The content should be mostly the same, the latter hasn't been updated
lately, though.
In your installation, the block isn't properly swigged. This is a
standard procedure, so I recommend you start from scratch, use

Hello,
I am experiencing problems with the tutorial on OOT development. I am
trying to implement the basic square_ff that is described here:
https://gnuradio.org/redmine/projects/gnuradio/wiki/OutOfTreeModules
and I get the following error:
File "MYPATHTOMODULE/Gnuradio/top_block.py", line 26
Hi Heitor,
if the same applies to you just displaying e.g. 10MHz of bandwidth with
uhd_fft, you probably have a hefty oscillator offset, either on the N210
10MHz reference or your signal generator. What generates your signal,
and which LEDs are active on your N210?
Best regards,

Hi
I'm trying to do a basic spectrum sense
with a USRP N210 kit and gnuradio.
I made a literature
research and noted that the “usrp_spectrum_sense.py” code was
used in some articles. But when transmit some
signal in a certain frequecy and execute the
“usrp_spectrum_sense.py”, the signal is found

You're going to have to decide what *symbol rate* want, and whether the
resulting signal bandwidth fits into your 1M sample rate.

Hi GRC companions
Has anyone used GRC to acquire a large range RF spectral survey?
Basically, step from range to range, and save the output in a (text)
file. I would like to be able to average each frequency/range for some
(variable) period of time, or do peak hold, much like some of the nice
Hi,
Anyone know or managed to implement the time command using a message port to
the UHD Source Block ?
I believe time commands are not implemented in the latest GNURadio gr-uhd ? Is
that correct ?
Thanks,

Dear mailing list,
we are trying to create a status overview of our receiver by using the
control ports feature. For most of our custom made blocks this works
very well and we can see the exported variables.
But for a few blocks the exported variables do not show up in the
control port monit
Hi,
I believe the problem with the 'small polyphase channelization application'
that I posted to the list could be related to the polyphase channelizer
block downsampling the channels, and consequently insufficient samples are
making it to the PHY receivers for them to decode packets.
I would like
