Dear Marcus and Bloessl,
Thanks for the reply. I also notice the fully functional gr-ieee802-11
package provide by Bloessl. Previously I thought it's only PHY, but as

My question arose from a comment that Jonathan made on one of the pull
requests
in gnuradio (#293).
If we have a set function in a gr block that sets some private variable
that is
used in the work function, do we need to protect it to make the whole
operation thread safe?
Is this a standard pract

Hi all,
It seems this is a ridiculous question, however, I didn't find any solution
for my problem.
I have already a bunch of custom blocks connected to each other which play
role as a transmitter (tx). I want to connect tx to a fir filter by using
fir_filter_ccc block. I set the filter taps with

Hello Mostafa,
filtering is a inherently lossy operation: it's an operation that
involves multiplication and addition of floating point numbers.
Matlab internally uses double (float64) values, whereas GNU Radio,
usually, uses single precision (float32) numbers for performance reasons.
Now, without
Hello,
I use the vector_source_x and vector_sinc_x blocks quite a lot for
testing, debugging and simulations, even with quite large input and
output data streams.
Therefore I was looking in speeding up the feeding and retrieval of data
by implementing the Python buffer interface [0] that permits
Hi John,
I have been trying at this all day! Not familiar with the async message stuff,
I have tried putting ‘sleep()’ in the source block, I have tried a throttle
outside it and even discarding the first X items just before the UHD sink to
flush the buffer away.
This all causes weird underflo
Is "forecast()"" need to be protected in such a case as well?
just searching on the web i realized that no operation can be assumed
atomic, so
I guess every single set_ method (even if it assigns a
float/int/short/char) needs to be protected...is this an overkill?

H.. I've never done burst transmissions with a 2x MIMO case. That may
or may not put a minor wrinkle in things. Let's go for the gusto and try
this anyway...
(or were you not looking for a burst transmission?)
This assumes you're using a relatively recent (past couple months?) build
of UHD
Also, I would have sent you a sample flow graph.. but the computer I'm in
front of has an embarrassingly old version of GR.

Hi Achilleas,
short answer: no, it doesn't need protection.
long answer: as long as the only one calling forecast() is the
thread-per-block (==default) scheduler, don't worry, it will never
concurrently run with work(), because it only gets called whe
Hi guys,
I think I have said it all in the title, any ideas how I can get create tx_time
in a transmit flow graph with a USRP UHD sink? I know that UHD source spits out
rx_time, but I don't have a UHD source in my flow graph, and if I did how would
I mux in the tag into my tx streams?
Cheers!
Greeting,
After building up some strong Matlab's prototype of my 802.11 receiver, I
have to make really big and complicated GUI with lot of button's, plots,
different tabs etc.
And my question is simple:
Any way to output complex data collected by USRP from grc to any other
