Martin,

 I have no idea how or why, but it magically works now.  Must have
heard you were on the case :D  Thank you!

Re: [Discuss-gnuradio] GNURadio autmatic gain adjustment

2016-06-02 Thread Simon Olvhammar


Hi Ben,
I have implemented a function to dynamically change my system gain based 
on sample distribution (to utilize full range of A/D converter). However 
I'm wondering why the sample values have a dependance on sample rate.

Hi Simon -

Just to make sure I'm understanding your question correctly: are you 
asking how to dynamically change your system gain or scale your 
samples so that you are using the full range [-1, +1]?

Hi,

In my GNURadio program I need to determine the correct gain in
order to fully utilize the dynamic range of the A/D converter of
the Ettus USRP x310.
I currently have implemented a automatic function for this using
the probe samples block and make sure that values stays just
within -1 > +1. I.e I check the distribution and make sure a
certain percentage of the values doesnt go above a threshold value.
However the values seems to have a dependence on sample rates, how
should I think here? Anyone else that have implemented this using
the probe block, what was your method?

Re: [Discuss-gnuradio] Testing 'noblock' Class

Dave,

what I did was

1. gr_modtool add -t noblock fo. Answer 'yes' when asked for a QA file.
2. Add a silly function to the new class
3. Populate the QA files
4. 'make test'

That's it. Worked fine.

Hi,

You can't.

The whole _impl coding pattern is specifically designed to hide the
internals to outsiders and as such, you just can't extend it from an
outside project.

Hi Andrej and all,

I have some experience with OOT modules - I've developed two OOT
projects (gr-gsm and Multi-RTL). And this is part of the problem - I've
played a bit with GNU Radio, I'm familiar with portions of GNU Radio's
source code, but I still don't know how to use inheritance to extend
existing blocks (something that in a lot of cases would make perfect sense).

I can modify GNU Radio source - but this way I will create a new version
of GNU Radio (specific for needs of my project) that users of my
projects will have to install. In comparison with that copying the
signal processing block's code to my project in order to add few lines
is a lot better option (in terms of amount of code that need to be
maintained, distributed and installed). And the point is to make things
easier not harder for everyone. If a GNU Radio's gurus tell me that
copying the source code is the best option in this situation and I that
shouldn't try to do that with use of inheritance, I'll be able to live
with that answer :).

P.S. please respond also to the mailing-list so others can benefit from
your responses.

Best Regards,
Piotr Krysik

Hi Andrej,

There are cases when my modifications could benefit others (on a side
note: in my opinion what would benefit everyone would be ability to
access setters of all of the blocks with use of stream tags and
messages), but there are also cases when I want to add some
modifications specific to my project and it doesn't make sense to even
try to make these changes included in the GNU Radio.

If I can inherit from *_impl classes - are you able to present how to do
it? *_impl.h headers are not installed together with GNU Radio so I'm
not able include them. And this is just a start - then I don't know how
prepare CMake files so derived class is linked correctly, and how to
prepare SWIG input file. If you are able to spare some time to describe
it I would greatly appreciate that.

Piotr
