Hi all,
I've some doubts on the GRC block PSK_Demod.
I tried to analyze the inner functions called in the /psk_demod block/ in
order to understand the algorithms approachs implemented for synchronism
recovery.
/psk_demod/ derives from /generic_demod/ and the latter can be found in
Works like a charm now, thanks for the help Martin.

Hi,
I'd like to receive a BPSK signal (recovering the phase/freq and timing
synchronism), not differential coded and in particular not shaped by a srrc
filter (rect pulse).
I guess that psk_demod.py supports only srrc shaped signal and that
digital_mpsk_receiver_cc supports only differential coded
Hi luca,
check out the examples in gr-digital/examples/demod.
You can set the filter taps as you wish, and do the same with the
modulation used.

Dear Gnuradio Mailing List,
I created a gr-modtool block on my Ubuntu machine; it works well, but I
want to run it on my Gentoo machine. At first, I thought I could just copy over
the module in dist-packages, but that doesn't seem to work:
I copied my custom module from:

You need to re-compile the source of the module in the gentoo computer
because the libs and so many things is diferent in Gentoo vs Ubuntu
copy all project created by gr-modtool from ubuntu to gentoo and run in
gentoo:
cd /path/your_blocks
rm build/ -rf
mkdir build
cd build
cmake ../
make
Hello!
As to introduct me, im very new to GnuRadio and the general topic of SDR.
However, i have a project in which i should implement a very basic way of
sending packets. This given packet format has a constant preamble and a
constant length of appended databits. For detecting those out of a

You have a few options. You can build a digital tx/rx in GRC, run an
example like tunnel.py, etc. I've also created a set of examples with a

Hi,
Is there a block in gnuradio that would watch stream tags and pad
zeros into the stream when a USRP drops packets. This would allow
other processing blocks to assume that outgoing and incoming IQ
streams are always in sync, which would help in many of the
applications that I'm working with.
Dear tzopik,

My next step is to do a phase-compensation for one of the USRPs so that
