Re: [Discuss-gnuradio] [PyBOMBS] Need your help!
Hi, Today, I have tried installing gnuradio on Antergos (Arch Linux based distro) using pybombs. Antergos ships Python3 as it's default python version and Cheetah seems to be incompatible with Python3. The build fails due to the unmet dependency of Cheetah template engine. The successful builds on Ubuntu 16.04 reported in this thread are because Ubuntu 16.04 claims to be shipping Python3.5.1 as it's default Python version, but it still has a good support for Python2.7.x. This issue of replacing Cheetah is slightly discussed at [1].

Hi Ravi, > The build fails due to the unmet dependency of Cheetah template engine. exactly that's why we depend on Python2 packages in python.lwr: category: baseline inherit: autoconf satisfy: deb: python2.7 && python-dev rpm: python-devel >= 2.7 cmd: python --version >= 2.7 pacman: python2 >= 2.7 port: python27 >= 2.7 vars: config_opt: --enable-shared Notice the pacman line! So, if GNU Radio is currently building, you should have an install python2. If you don't, there's a bug in dependency checking. I'd expect all our build scripts to explicitely specify that the python2 executable should be used. If you can give an actual bug report of where exactly building fails, this is probably something that's fixable. Also, you said "need your help!", but then didn't ask a question or what exactly we should be helping you with :) So if I didn't hit the spot here, please explain what it is that you need help with.

Hi Marcus, I had already installed python2 before running pybombs on my PC. I have just rechecked installing gnuradio with sudo privileges and it seems to be picking the python2 version correctly. P.S. I was replying to Martin's mail dated http://lists.gnu.org/archive/html/discuss-gnuradio/2016-05/msg00242.html.

I'm going through the code that calls python at build time. Is this a fresh, clean Antergos, or did you manually install different versions of python through something that is not pacman?

[Discuss-gnuradio] OFDM IFFT calculate
Hi all, The file, /gr-fft/lib/fft_vcc_fftw.cc(http://goo.gl/X8WNPh), changes domain from frequency to time using IFFT(Inverse-Fast-Fourier-Transform). It takes parallel subcarriers in frequency-domain (it is defined 'in' in the file) and converts it into time-domain(it is defined 'out'). I can understand how get inputs to 'd_fft', but I don't know about d_fft->execute() that compute the fft. I can't find its' implementation in anywhere so that I can't understand what happen in this function. Could anyone tell me how compute the fft in the function ? Thanks. ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
[Discuss-gnuradio] accumulate spectrum
Dear All, I'm new to Gnu Radio. I looked carefully to the doc and tutorials but could not find any simple answer to my problem. I have a radio signal from which I'm able to visualize the FFT in GNU Radio Companion. Now I would like to save the FFT (more exactly the magnitude squared, or the spectrum) accumulated over a given period of time (the average over time) into a file. I found the following blocks in GRC that seem to be helpful: - stream to vector - FFT - complex to mag - file sink However I did not manage to save any accumulated spectrum... Any help (eg a woking example) would be very welcome! Thanks in advance. Adellain ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio

Why are you using a revision of that file from 2012? That is not what you should do. Select "branch: Master" from the drop-down menu; you should be looking at http://gnuradio.org/redmine/projects/gnuradio/repository/entry/gr-fft/lib/fft_vcc_fftw.cc?rev=master . Reading versions of code that no-one uses anymore doesn't help you ! > I can understand how get inputs to 'd_fft', but I don't know about d_fft->execute() that compute the fft. So, here's how you approach something like this: Find out what "d_fft" is. For that, you often need to look in the .h file to your .cc. There you'll find out which class type d_fft has. Find that type's definition. Or, you could just go to and search for "execute" in the search box. That'll tell you the classes that have a method called "execute", and you can access the documentation to these. > I can't find its' implementation in anywhere so that I can't > understand what happen in this function. A DFT is performed, by calling the fftwf_execute function of the FFTw library, which really, just executes a fast DFT.

And because "DFT" is not totally unambiguous (because there are different normalization conventions out there), if you care for the actual formula, it's on http://www.fftw.org/doc/The-1d-Discrete-Fourier-Transform-_0028DFT_0029.html#The-1d-Discrete-Fourier-Transform-_0028DFT_0029 i.e. the backwards (inverse) n-point FFT is really just plain, old, boring, textbook No normalization.
