The tone reservation PAPR reduction block used with the DVB-T2
transmitter in gr-dtv may be interesting for you. It uses a ton of
floating point calculations.

Even though it uses Volk kernels extensively,
Hi,
for my thesis I'm making "porting" of gnuradio blocks over CUDA..
For the moment,I've bring basick blocks,FIR filter,FFT,an FM receiver(not
so good due to latency) and I'm working with ofdm..I still need to
implement IIR filter
Which other blocks do you think that could be nice(useful,get
perf
So, I first noticed this problem with my main GNURadio install (3.7.5 on
Debian Jessie) but I've reproduced it on a brand new 3.7.7.1 live USB.
Basically I'm looking at two frequency sinks. One of them centered at 0 and
one centered at 16kHz. I have a single signal source input to both sinks,

Hello Nathan
Can you provide some information on how you are building VOLK?
I download the VOLK file from the git, cause the master of gnuradio does
not have volk included. https://github.com/gnuradio/volk And then I just
follow the instruction in the building website
$ mkdir build
$ cd build
$ c
ok until 3.8 how can I use this block without making mistakes?
If for example want the following polynomials (copy from [1])
x^4 + x^3 + x^0 = 0x19
x^5 + x^3 + x^0 = 0x29
x^6 + x^5 + x^0 = 0x61
do I have to set the length to 5,6,7 respecti
There's a GR_REQUIRED_COMPONENTS CMake variable[e.g. 1]; add FILTER.
Best regards,
Marcus

Agree. This was a poor implementation decision by someone w
Solved.
I needed just to type "sudo ldconfig" and afterwards it works like a charm.
Thanks to all who read the problem.

Hi all,
I found the problem.
In my OOT block, I try to use mmse_fir_interpolator. Thus, in the
my_block_impl.h file I use the following code to include the fir
interpolator:
*#include *
But when I run ctest for my block, I got the following error:
*ImportError:

Hi Shaunwag,
rtl-sdr doesn't belong inside your GNU radio source tree, and it never
did. Both things are unrelated.
Compile rtl-sdr anywhere you've downloaded it, "make install" it;
install GNU Radio.
After both, build the gr-osmosdr module, and you will get GNU Radio
blocks that allow you to acce
HI Thanasis,
first things first: That is gr::digital::scrambler_bb, which has doxygen
documentation [1].
The length is really just the length of the underlying shift register --
which ought to be at least (order of generator poly)+1, ie.
floor(log2(mask))+1
I recommend having a quick glance at its
11 matches
