[Discuss-gnuradio] Error while building openLTE code on USRP

2013-09-30 Thread Dincer Beken 
Hi all,

I am new to Gnuradio and USRP. I want to try the openLTE Project on my USRP 
N210.

During the cmake process I am getting the following errors:


CMake Warning at CMakeLists.txt:92 (find_package): Could not find a 
configuration file for package "Gnuradio" that is compatible with requested 
version "3.7.0".

The following configuration files were considered but not accepted:

/usr/local/lib/cmake/gnuradio/GnuradioConfig.cmake, version: 3.8.git.0


Also since I am not using one of the following devices:
I also get :

-- checking for module 'gnuradio-osmosdr' -- package 'gnuradio-osmosdr' not 
found -- Could NOT find GNURADIO_OSMOSDR (missing: GNURADIO_OSMOSDR_LIBRARIES

After that, I changed in the cmake file the required Gnuradio Version manually 
to 3.8. Now I am getting only the OSMO / RTL errors:

How can I ignore those libraries or replace them?
And can I use this code on the USRP?

Re: [Discuss-gnuradio] Error while building openLTE code on USRP

2013-09-30 Thread Dincer Beken 
Sorry but I think I mailed to early.

On a normal gnuradio distribution from the build-gnuradio.py -m" code on 
Fedora, I did not experience the problems while build and install.
I am checking out the code right now..

Regarding OSMO and RTL-SDR, I did understand it like the libraries can detect 
and work with USRP, so that's probably clear, too.
When using those libraries with USRP, are there any specific changes that I 
should make for some blocks etc.?

Regards,
Dincer

Read the error. This has nothing to do with Volk. It's trying to open
a file that doesn't exist or exists in a different path than expected.

[Discuss-gnuradio] I/Q samples and Analytic Signals

2013-09-30 Thread Lucas Ingles 
Hello to all,

I am using GNU Radio to study digital communications systems.
I have been working on the basic FM receiver with RTL-SDR for a while.

I was trying to find out what is the theory behind the complex I/Q samples.
What I discovered is that I/Q samples are first related  to analytic
signals (the pre envelope) and then to the complex envelope of the signal
(the complex signal in base band).
In fact, what RTL-SDR outputs to the flow graph is the complex base
band signal, in other words, the signal translated to base band with just
the positive or negative portion of the spectrum.

Please, can someone with more experience confirm to me if I am correct?
Can someone please recommend me some reference books about the theory of
I/Q samples?

Thanks very much in advance,
Lucas Lorenzi Ingles

good choice!

There is actually a page on this topic on the web site:
http://gnuradio.org/redmine/projects/gnuradio/wiki/SuggestedReading

Perhaps this helps.

Complex baseband is in fact one of the most important topics to
understand.

Re: [Discuss-gnuradio] I/Q samples and Analytic Signals

2013-09-30 Thread Lucas Ingles 
Thanks very much for the help!
I obtained the book (fifth edition) and already read whole section 2.1
(Band pass and Low pass Signals).
That was exactly what I was looking for.

I have one more doubt. Figure 2.1-6 in page 25 shows a real demodulator (I
attached the figure here).
This is not the same block diagram of the demodulador that we have inside
Elonics E4000 Tuner (zero-IF demodulador).
We don't have a Hilbert transformer inside the zero-IF demodulator. We have
just two paths, one multiplying by cos() and the other by sin().
Perhaps the Hilbert transform is implemented by handling the I and Q
components as a complex number I+jQ inside GNU Radio?
Can someone please explain to me how the zero-IF demodulator is related to
the real demodulator shown in the book?

Thanks very much again,
Lucas Lorenzi Ingles
