hey. I am trying to synchronize transmissions from multiply relays using
gnuradio and usrp b200 radios. I would prefer to achieve this in GRC but i
cannot figure out how to to do this. If it is not possible in GRC, then
please tell me how i can achieve synchronization using python code. Thank
you.
Hello Mohammad Hasan:
I think you already posted this to the usrp-users list. I replied to you
there, and I'll repeat it here.
The answer depends on what you want to do in your research project. There
are many things to consider, such as the type of interface to the host
computer you need/want, h
Hello!
What is the difference between a general block 1: 1 and a sync block?

header.
Following the information posted on

Hi Guys,
I have a new question about the type of the data in the output of the
source (RTL2832). The signal is represented with complex numbers! why? What
do this complex numbers means physically?
In my head the data in the output should be real, should it?

I've merged this into 3.7.5git master. Thanks again for your work on
this--it will make a big difference to those compiling GNU Radio on
multi-core machines.

Thank you very much for your effort. I will have a look into it.
I came up with an other idea. I put my block and the filter-block in one
hier-block (written in python, not in the GRC of course), in which I can
pass the filter-block as parameter to my block, and use only that
hier-block in the

See if that works for you (untested):

Why not write a patch to the existing filter block(s): add the message

Hi,
how can I pass an other block from my flowgraph to a self written block
in the gnuradio-companion? What I want to do is invoking a method of
that passed block in my own one (or maybe there's an other way to do that?).
I have tried passing the ID of the block to a parameter of type "raw",
15 matches
