Hi,I was going through Jonathan's hack to receive multiple NBFM at once.I am
really impressed.I would like to know whether i haveto use
gr.analysisfilterbank and then attach a FMmodulation block for multiple Tx
transmission too.I am trying to send multiple mp3 playlist over the fm spectrum

your right, my bad.. not sure what i was looking at...
the ubuntu build guide in the wiki has the instructions for setting correct
usrp/usb perms which work for debain also

Hi!
I have successfully implemented the Reed-Solomon coding scheme in gr.atsc on
USRP, the receiver can receive packets now. But after running tons of
experimentation and comparing the performance between DQPSK without coding and
DQPSK with Reed-Solomon, I cannot observe any performance improve
Hi, Jason
Thank you for your help! Good man! Actually, after running lots of experiments,
I found the reason for my problem. One of my USRP is broken and it can only
serve as a TX, when playing as RX, that weird thing would happen.
Actually, I am not transmitting one large batch file continuous

Hello Ben,
When I try to run the version of simple_mac that you posted, I get an error.
It seems like an infinite loop that prints to stdout:
2nstreams:
It happens at the call to fg.rxpath.start() .
Do you have the same problem?
Thanks,

Yeah, I know, and I also looked for the files in gnuradio/usrp2/ and found
some of them (strobe_gen.v and extram_interface.v) in another places. But
u2_basic.v and fifo_...v seems to be realy missing. I couldn't find them
anywhere on the trunk (rev 10991).

Not to complicate things, but this won't work as expected. There are
many binary packages for Ubuntu, and the 'gnuradio' package is simply a
meta-package that depends on the others, for ease of installation. So

If you have apt-get, you have dpkg too.

Hello,
I tried the DBPSK and DQPSK scheme with benchmark_tx.py and benchmark_rx.py. I
found there is a problem with USRP. After having TX and RX rest for
20 mins, the communication between them are so good that the PDR
detected at the RX is almost 99%, but after those two USRPs run for a
while, sa

Hi,
it's just a nitpick, really, but I'd like to vote for chucking out the
close() calls in gr.file_descriptor_{sink,source} (in the destructors).
I've been working with these blocks for talking across pipes, and I
constantly run into warnings because files get closed when I don't want
them to. S
