2-ASK is practically BPSK plus really bad DC offset (hey, that
description is even an instruction on how to build a 2-ASK modulator) :)
So, Muller&Mueller (Müller&Muller? Mueller&Müller?) should work just as
fine, if you cut out the DC component (HPF), shouldn't it?

I built it myself in usr local.
The source exists at github and sourceforge. Apparently SF is the
original. I built both versions and neither is found by gnuradio in the
build process.
The contents /usr/local/include/log4cpp is at this pastebin.

Hi,
if you've built it yourself, chances are that automatic tools like
CMake's find_package or the general pkg_config can't find it, because
you didn't put the right files in the distro-typical places.
Try running
pkg_config --libs log4cpp
If that fails: Please make sure the installation put th
Dear all,
I am using gr-ieee802_11 Transceiver to analyze wifi signals.
I receive samples and retransmit the same IQ samples wit Tx and save
them in file, but when I try to use that IQ samples from file to receive
them from file source some packets are not received, even though they
are successful
Hi Seref,
Sorry,

I'm not quite sure I get the full idea of what exactly you're doing.

No, f_sample is the sampling rate. Remember: every "frequency domain"
1024-vector you've stored corresponds to 1024 time samples (hence my
longish explanation of what happens to samples). 1024 time-domain
samples take exactly 1024 sampling periods T_sample to capture, and T = 1/f.
Best regards,

Dear all
Are there any block available in GRC to sync byte frames?
I want to transmit a fixed amount of bytes over the air and start the
postprocessing at Rx, when the fixed frame is noticed.
Thank you all

Hi Marcus,
thank your very much for your reply . In Pictures attached there are my
receiver and transmitter. So with HackRf I have received some wifi packets.
And in my transmitter I read the Pcap file which contains those wifi packets
that I received and sending them all to the transmitter to cre
Hyphen instead of underscore.
pkg-config --libs log4cpp
-L/usr/local/lib64 -llog4cpp
So pkg-config finds the library. Note I got the same problem regarding
not finding log4cpp when I used the opensuse package manager version
instead of making my own in /usr/src.

Hi Ellie,
absolutely was a pleasure, and not at all requiring any patience!
I don't know if I already did that, but maybe Michael Ossmann's DSP/SDR
tutorials are something for you! You can find links to those and other
resources on our wiki,

Hi ,
I am sorry I have send on nabble and did not know that willl add only as
thumbnails. I can send grc flow graph but i have changed the original codes
so without those cpp files will it work. I dont know but I can send the
whole project. I can also send whole files if have time to check it. I

Hi Sebastian,
awesome! :) I've had a look at your code, it looks like a sensible way to
start tackling this feature.
About the parameter values, thanks for bringing that up! It sure does
complicate things, but from what I can see your suggestion sounds like a
good plan.
Best regards,

That file is found twice. Is that the problem? If not, which do I
replace? Or perhaps both. Or does one file cause the other file to be
updated?

Thank you very much for the helpful suggestions; my setup is working very
nicely now! I changed the sample rate to 2MS/s, and the bandwidth to samp_rate
instead of bw as you suggested, and tested it again with the function generator
at 20 kHz. This time, the frequencies match exactly where they
On opensuse tumbleweed I needed to install the log4cpp-devel package. The
