Thanks Marcus for your valuable information .
Now as per you have said that the usrp/gnuradio doesnt do any default
demodulation , that means if i apply a demodulation technique to the
captured file from usrp_rx_cfile.py , i will get the required output.For
example if i apply GMSK demodulation to
Thanks nick for your immediate reply , if we have different demodulation
modules and as i have learnt recently that usrp/gnuradio does not do any
default demodulation , than what captured file from usrp_rx_cfile contains
... is that the captured file contains the complete baseband information
Hi all,
This is a little bit offtopic for this mailing list, but I can't find
a better place to ask this question.
We're doing an open-source project on WiMAX decoding
(http://code.google.com/p/wimax-scanner/) and at this point we have a
trouble with correct subchannelization of DL-PUSC, so
hi josh:
Thank you for your last e-mail.I am sorry I did not mention the version of GRC
I used,and it is 3.2.2(GNU Radio is 3.3.3).
And I found the probe_function block as you said.I use a scope block to connect
to the probe_function block to see the output
of the blcok.I also put the bpsk
Hello every one...
i am new in gnuradio...
i start tracing usrp_rx_cfile...
i want to find the hardware interaction point where data is received by
gnuradio from usrp...
or
from where gnuradio code starts processing take data from usrp...
I found a function read in file fusb_generic which
the demodulation and modulation is done in GNU Radio. the raw digitized
signal from USRP will be proccessed by gnu radio either we want to
filtered, do FFT, demodulate and etc. all is done using GNU Radio.
USRP is the hardware to interfare the digital world with the analog world..

Hi all,
I'm transmitting a packet to 2.4G band using RFX2400 on USRP1 and observed
this problem:
Once in a while, the transmission stops in the middle of the packet being
transmitted.
Does anyone know if 1) there is any TX amp control line which is
controlled by the FPGA and in what
I have some code that lives on top of Gnu Radio, and I think I'm having
a code-generation issue with GCC. The binaries work on all
my machines, but on a customers machine, it raises an Illegal
Instruction exception. I generated the code on a 32-bit Intel Core
machine, on Fedora 12. The

Hello Guys,
I am experiencing some problems in transmitting/receiving at frequencies around
900MHz for WBX board. While, I am able to do so cleanly at 900MHz, other center
frequencies are not.
The signal bandwidth : 50 KHz
The sampling frequency: 200 KHz
I have tried 901MHz , 900.1MHz, 910MHz

Hello Jason,
Thank you for the instant reply. Here are the responses to your question:
The transceiver set-up is really basic:
TX
Random src -- DQPSK MOD -- Pulse Shape -- UHD SINK
RX
UHD SOURCE -- FFT block
so,
Signal amplitude? 1
Gain setting? 0dB at TX and RX sides

I have an Ettus 2 and an RFX2400 that I don't need anymore. I used them a
couple times and they work great. If you're interested just drop me a line.

Ok, we've found the problem ourselves:

Now we can see DL-MAP in our test captures.

Ok ok wrong audience for inaccurate branding. USRP2 is for sale. I guess
Ettus1 named the product USRP not Ettus.
