You may try 'VideoLAN'. It supports IP streaming output and input. Then you
can make your TX RX as an IP tunnel.

Hi,
I connect dbpsk modulator to dbpsk demodulator. I expected that input and
output must be the same but it is not.
for instance input vector is (0, 1, 1) while
output vector is (0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 1, 0, 0, 0, 1, 1, 0,
0, 0, 0). what is the reason?
help is appreciated.

hi,
the code I wrote is
#!/usr/bin/env python
from gnuradio import gr, gru, modulation_utils
from gnuradio import blks2
src_data = (0,1,1)
Bsrc = gr.vector_source_b(src_data,False)
Bsink = gr.vector_sink_b()
def build_graph():
fg = gr.top_block ()
Bmod = blks2.

I was working on qpsk receiving with GNU radio and I was wondering if
these are something we should change.
1. The qpsk constellation in the current code seems to be (1,0),
(0,1j), (-1,0), (0,-1j). Should it be rotated by 45 degrees?
2. I understand that in the current mpsk_receiver_cc

Thanks! Looks like I am using some old
hi,
I try to use benchmark in gnuradio. When I use gmsk which is default
modulation scheme there is not error in detection of packets in the receiver
but when I use other modulation options like dbpsk detection of all packets
fail.
why does it happen?
thanks,
Mehdi

Juha, Brian,
I am working on a research project that involves wide-band spectral
estimation with the USRP. In this case, the bottleneck is USB 2.0,
which is why I need to implement my sample selection algorithm on the
FPGA.
Thanks for your interest.

Has anyone downloaded Chiara's VMware GNU Radio image? Did it work for
you? When I unzip it I get a report of a CRC fail error, and the VM
machine is reported as corrupt by VMware Server. Is it just my copy or
is the source file broken?
Thanks
Cheers
