Hi, All
I have very trouble
My experiment enviroment isUBUNTU 11.04 , USRP N200, DBSRX2 ,active
antenna and gnuradio
I am worrying about good software GPS receiver is not exist .
I want to receive L1 signal , and want to demodulate that signal
However GPS signal is used Spread spectrum modulation
Sure,
I am using the code on the trodeau repository and the ofdm 1tx-1rx
works, however when I try to use the 2tx-1tx with the alamouti it
doesn't.
I am not using USRPs now, but just 2 channel models without noise and offset.
The tx codes 2 consecutive symbols as the alamouti says and add 1

Hi,
This is great work.
I updated my Gnu Radio to the latest code using Marcus build-gnuradio
script but I did not get this new selector block.
Can someone please explain me how can I integrate this new selector
block into my gnuradio/GRC installation on Ubuntu.
Thanks,
Khalid.

Hi,
I have a basic question from rx_samples_to_file.cpp example. When exactly
USRP N210 gets tuned or locked?
If I issue two commands
of uhd::stream_cmd_t::STREAM_MODE_NUM_SAMPS_AND_DONE, will the usrp will be
re-tuned between them.
Thanks,
Khalid.

Hi folks,
My group is using USRPs to do the task Kouki described, although our flow
diagram is a little different. We only use the USRP2 to receive the raw RF
data which is written to file. This data is processed to the point where
we decode the navigation bits, but no position is ever found. W

The work has not been merged into the official gnuradio master branch.

I am using th n210 and what is in my code is:
addresses = "addr0=" + self._addr_master + "," + "addr1=" + self._addr_slave
print addresses
self.uhd_usrp_sink_0 = uhd.usrp_sink(
device_addr=addresses,
io_type=uhd.io_type.COMPL

I'm currently testing UHD.
I use two USRPs with one SBX on each.
and I got GNU Radio 3.5.0rc0 on Ubuntu 10.10 and benchmark programs
supporting UHD.
When I run benchmark_tx/rx.py, however,
tx@ubuntu $ ./benchmark_tx.py -f 410M
rx@ubuntu $ ./benchmark_rx.py -f 410M
I can see 'dots' representing a
