Hi list,
I want to record a 5MHz wide bandwidth with usrp1 (equipped with dbsrx1 and
modified clock @ 52MHz), can anyone guide me how to do this, I am using
usrp_rx_cfile (using gnuradio-3.4.2 for special purpose) with
gain =52
decimation= 26
Please do let me know if I need to make any changes in
Having your complete general_work function wouldn't have hurt my
understanding much...
I really can't make out what you're trying to do without doubt.
Anyway, from the code below I think in *must at least* have the same
number of entries that your for loop has iterations; did you just try using
Hi gsmandvoip,
Your decimation seems about right (oh, I don't miss libusrp). I don't
think you need to change the example, but please be aware that libusrp
has become so obsolete that I don't even have the source code around
anymore.
I'm not totally sure you need to use libusrp to have openBTS
Dear Sir,
It is found that in newer version of gnuradio, the WX GUI Scope Sink
doesn't have a Persistence checkbox.
In this case how to get back the feature ..?

Dear Sir,
The new WX GUI Scope Sink behaves slightly differently from the previous
one.
How come it only plots the center part (as circled), how to make it plot
the full graph without changing the time/div of x-axis?

I followed the tutorial to generate a module and all was well. My square
module worked. I then created a new module invert_bb. This also worked.
So far so good. Now a few days later on I get AttributeError: 'module'

Hi Mike,
my first guess if making from scratch didn't help: maybe your module's
name is conflicting with an existing module, or there are remnants of a
former installation lying around for some reasons.
You could try uninstalling your module via make uninstall, and then
running a python trying to
Hi Mike, is it possible that you are responding to my response on
gnuradio by replying to the usrp-users digest?
I'm a little confused...
The stopped working might be explained by the fact that as soon as you
update a library (ie. as soon as you update GNU Radio),
you need to rebuild all software
Thank you for your notes Marcus,
As you said this is unnecessary process to point to the input_items in a
for loop!!
However, this is not the problem because I checked that I have the same
number of iteration in the for loop as the number of input ports.
The problem is somewhere else. *Again I
As I said, you should use the gdb debugging approach to find the mistake.
gr_complex **in = (gr_complex) input_items; shouldn't compile, because
the types are incompatible.
I can't help you any further with the information you're offering.
Please share at least your complete general_work method,
Hi Sylvain,
Thanks for looking at this code. I really appreciate the feedback.

Hi,
For the encoder/decoder, you're totally right. I didn't free any of the
temporary matrices. I just updated those classes with gsl_matrix_free calls.
Ok good.
Whenever we move to a more efficient implementation that doesn't use
GSL for GF2 operation, it would probably make sense to have
Yes you're right about casting between in and input_items, however, I
think this problem is somehow related to the large number input ports! I

Here is the whole block:

I forgot to say, I'm using Qtcreator to debug my GNURadio codes I do not

The prgram is terminated at line in which I read from the input for the

for (int j=0; jN_FS_phich(d_normal_cp); j++)

Hi Marcus, list,
Thanks for swift response.
You are right about openBTS, but at the same time I am using really old
system (12.04) havent formatted for years due to its required installation,
which can turn into real time consuming tasks thats why dragging it as long
as I can avoid above
Mostafa,
I do not think you have truly run the complete codes using Qtcreator,
because that doesn't have a gnuradio runtime (the scheduler).
At the other hand, your problem sounds more like a c++ coding error rather
than gnuradio-specific.
The helpful approach is
1). Put up the OOT into github.
