hello, i would like to get list advice about the best way to demodulate pulse
position modulation; i was thinking about envelope detection as in am, followed
by a custom block to do packet start recognition and bits decision, but i am
not sure it is the best approach...
The ppm would be at 1mbps
Hi,
Are there any good (standard) tests for the flex2400, or can anyone tell
me what I'm doing wrong?
I tested the BasicRX and BasicTX boards by plugging a shielded wire
between them, running usrp_oscope.py, and running the
test_usrp_standard_tx script. Signal in, signal out - happiness, aft

Right place, wrong version.

Two problems have been identified with the 'unofficially' released 3.0.1
tarballs. Both are easy, one or two line fixes. So we're going to fix
these and re-release tarballs using the same version number, and retag
the SVN repository accordingly.
Tomorrow there will be new tarballs posted to the

There is only one revision number use
As GNU Radio now ships in a mega-tarball, which version numbers are assigned
to the individual modules? Are they pulled inline with the version number of
the release, e.g. gr-audio-oss-3.0.1?
That's the way I'd do it. (version set in Makefil.common, and pull
from that in individual pkg Ma

On the DBSRX, bit 0 is used for the clock, so it is already an output.
Everything else is available.
On the TVRX, all 16 bits are available.

In particular, DBS_RX and TV_RX.

Hi Eric,
I did some calculations and something doesn't add up. As I mentioned
in my last email, I am using usrp.sink_s. Thus, my samples are real
shorts (16 bit). I verified the buffer size by printing out the buffer
allocation size in gnuradio-core/src/lib/runtime/gr_buffer.cc. The
size is 32KB.
Hi all-
I am demodulating an AM modulated waveform, and would like to display the
time series of the sideband in a window. I have code that uses the scope
sink to do this, but the magnitude is in units which I take to be
correlated to A/D raw values (ie, values near 2000). How do I convert

Is this while using pkgsrc? You're correct, the README.hacking in the
root of the tree is not pu
generate_all is also executed after a "gmake clean" since it removes
several files that are supplied in the tarball, which need to be
regenerated, causing the same problem.
So if we need generate_all to work anyway, probably the files it makes
shouldn't be in the tarball.
One of the things
G'day,
FYI: The inofficial release installs ChangeLog, README and attempts to install
README.hacking, which doesn't exist in the tarball. It also crjeates an empty

BTW: Is there any point at all to install these files if a user decided to

Hi,in the receive path, the decimation is handled by the rx_chain.v module. That module also takes care of the digital down conversion to baseband using the CORDIC algorithm.Oussama.

Hi,
For my work I need to do some time stamping on some signal samples. For this purpose I need to modify a little the FPGA on the USRP. I suppose .\usrp-0.12\fpga is the right place to look at. There's a bunch of HDL design files in the folder, I wonder which of them have been used to handle the
G'day Johnathan,
Ok, they are forming part of the distribution, but I've never seen and
obviously never missed them until now.
I didn't create a pkgsrc distribution for version 3.0 since it had other
problems that needed to be overcome and my working schedule was very tight at
that time. Hence
