I trying to run a GMSK mod/demod test under GRC. My objective is to
create a single GSM-like burst and to store it in a file. The waveform
should have defined bits (by now I assume them to be random).
Thus I created a flowgraph that looks like this
Random Source (fixed # of samples, no
Hi Alex - In MacPorts (currently), one can install any of the GNU Radio ports
with PortAudio using the +portaudio or +full variants. Neither is the default.
If GNU Radio is installed with the PortAudio option, can gqrx make use of it?
Or, does gqrx have to be configured (and built) using
Hi Michael,
I wasn't very clear in my original explanation so let me try again.
If you build gqrx using:
$ qmake
$ make
Then gqrx will be built without any portaudio specific code. It will
use gr-audio for both audio input and output, whcih in turn will use
the native OS X backend unless the
Just for the record.
If the selected floating-point hardware includes the NEON extension (e.g.
-mfpu='neon'), note that floating-point operations are not generated by
GCC's auto-vectorization pass unless -funsafe-math-optimizations is also
specified. This is because NEON hardware does not
Hi Alex - OK; that all makes sense. Thanks for the clarification. Next gqrx
update I'll add in a variant for +portaudio. And, I'll hopefully get the OSX
native audio fixed up in the next couple of weeks. In the meantime, if anyone
is using gqrx on OSX (via MacPorts or otherwise), I'd love
Hi,
I'm having hard time using GNU Radio to replace Simulink :)
I'd like to build a QA flowgraph (think of evaluating a BER vs. SNR
curve) to assess the performance of my signal processing chain. The
problem is that the signal processing chain starts with blocks passing
messages around, then
