Hi Marcus and Activecat,
Thank to you Activecat for your proposed solution to the question. The
method is very interesting to me to use *forecast* and *consume* or setting
right values in the io_signature.
As Marcus said it's better to use *interpolator* or *decimators* to change
the rates and I k

Hello Usman,
going from deploying an already existing GSM basestation software to
implementing a complete standard is a huge step.
Also, USRP1 is almost certainly not the device I'd chose for that task --
in can shuffle a maximum of 8MS/s over USB, and you need 5MS/s for up- and
downlink each for

I googled it and found a link to this email and an old gr-con mention.

Hello list,
I am planning to implement CDMA-UMTS protocol with USRP 1 and GNU Radio.
I've first established OpenBTS setup with USRP1 and OpenBTS 2.8. Now I want
to implement CDMA-UMTS in the same way as OpenBTS to establish a CDMA
mobile network.
Can anyone guide me about starting point like what

Well that doesn't make any sense. gr-qtgui looks for QT 4.2 or higher. It
should not have even been enabled without finding QT4 on your system. Are
you sure that's the

That one seems strange, being such an integral part of QT. But my guess is
that it's an API change in a QT version that we missed. (We'll be up
Ok, I'll try there. Do you have any idea what is the problem with QFile

Ok, well this is getting boring. For things like this, best to jump into

Hi Activecat, hi Mostafa,

The rate of data is really just a property of the values of the samples.
For example, a sine with a frequency of 1000 will have a period of 32
samples for a sample rate of 32000, if
make in gr-trellis folder works, but when I run again from build folder the
same error appears.

I am trying to build 3.7.3, and doxygen version is:

Hi everyone,
some of the European developers have been busy at the first EU hackfest
the last couple of days, here in Karlsruhe, Germany.
A lot of thanks go out to the powerline gang at KIT, who hosted the
whole thing and provided us with power, internets and a space to put our
laptops.
We
Pls stay on the list.

Unfortunatelly there is another error which is not reported by anybody

Hi Nemanja,
that issue has been fixed in more recent GR versions (it was a
incompatibility with old Boost versions).
If you do not wish to update GNU Radio, just replace
boost::random::mt19937 by boost::mt19937 in message_strobe_random_impl.

Hi BZS,
luckily, that's rather intuitive :) :
Using the complex to mag squared block you can get the sample "energy".
Using the max operation you can find the maximum in your vector
(==ofdm symbol), using integrate (with a decimation of vector length)

Hi Mostafa,
you will have to have all your sample streams at the same nominal
sampling rate (which again has nothing to do with the item rate you
described). You do that by resampling.
How you combine these streams is obviously totally part of what y

how calculate PAPR in OFDM with flow graph?
thanks??
