Hi all,
I am new to gnuradioand I want to implement Zero Forcing (ZF) and MMSE
equalizer in OFDM communication using gnuradio.
Which part need reconfiguration to implement them?
I use usrp bus series and gnuradio 3.7.0.
Thanks,
Zai___

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
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 to

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 us
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 AUDI
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 repeat)
