All,
I'm interested in, and looking into the Pi/4 QPSK modulation technique
(http://en.wikipedia.org/wiki/Phase-shift_keying#.CF.80_.2F4.E2.80.93QPSK).
Has anyone worked on this before and does anyone have any blocks or code that I
could use for reference while making my own? Any help, links, b

All,
I am running a basic PSK Mod block in one GRC flowgraph and another flowgraph
with a basic PSK Demod.
I am using two URSP N210s, one as transmit, one as receive and GNU Radio 3.7.5,
built on Ubuntu with Debugging Symbols.
If I start the PSK Mod, while the Demod flowgraph is running, I get
GNU Radio yourself
later on or if your signal processing needs demand C++ blocks at one point.

Hi,
Is it possible to create an OOT module written in Python to run on windows
without having to compile anything? I am hoping that I can drop a Python file
and a GRC file somewhere and have them just run, seeing as Python does not need
to compile anything.
I have GNU Radio installed with the
Hi,
I am in the process of creating a custom block for GRC - I have managed to
write the C++, compile and install it all on Linux, but I was hoping that it
would be simple to port that over to Windows (Maybe just place the right files
in the right places). When I did 'sudo make install' in the
Hi,
I am new to GNU Radio but have noticed something... When I create a PSK
modulated signal and output that to a constellation sink, why is the signal so
noisy? Why is the signal not in four perfect constellation points?
Signal Source -> PSK Mod -> Constellation Sink
Thanks,
Luke
