hi,
i would like to try the OFDM example but i cannot find the

the file being remove from the gnuradio-3.1.3.tar ?

Im learning about gnuradio for my final thesis (quite common i see) and i
wanted to show a simple FFT of a simple signal (or noise) but the only thing
i get the GUI working for is audio input from the microphone. Running it
with a generated signal causes the program to freeze.
Here is my code: (ive
There are plans now...
Any example code would help

This is normal since there is no sampling rate control in your code and your
CPU will be eaten. To overcome this problem use gr.throttle API in you code.

Here is another series of patches. These come in 3 flavours:
Independent, general cleanups and additions, which neither influence API nor
ABI

Hello, all!
We are using RFX2400 to transmit some signals. As known, transmit power of that
board is said to be 50mW shown on the datasheet and the default value of
--tx-amplitude in benchmark_tx.py file is 12000. Can we say the real
transmitted signal power is 50mW which is correspoding to 120

If I'm using the USRP in 8-bit sample mode, can I get 16Msps complex
data over to the host, or am I maxed out at
8Msps?

Stefan, thanks for these!
I'll get this applied either today or tomorrow, and will coordinate
with George on the earlier one.

It'll do 16MS/s in 8-bit.

Hi Everyone, I've been working with Thomas Schmid's old 802.1.54
demodulation code. I've got it running well on the original USRP and
have been trying to get the code to work with the USRP2. I basically
just changed out the source block and yet could not properly
demodulate a packet.

Thanks for the replies.
I have checked the Quadrature values and they are indeed 0.0
I had already followed the steps to flash the SD card (using the one
that came with the USRP2) and used the firmware (txrx.bin) that

When I use 8-bit samples with decim=8 or higher, things are peachy.
But when I use decim=16 with 8-bits samples, I get a continuous stream
of -423dB out of the FFT Log Power sink.

Is the octaverc configuration file referred in the link you sent me the same in
/usr/share/octave/3.0.0/m/startup folder?
How is the "read_complex_binary()" script used? Can it be used in a python
script and if so, what should be imported?
Thanks

According to this:
http://gnuradio.org/trac/browser/gnuradio/trunk/gr-usrp/apps/usrp_rx_cfile.cc#L87
if you dont like half band filters or you want to decimate by 4,
"std_4rx_0tx.rbf" is the firmware for you

Hi,
When working with 8 bit samples, you must disable FPGA halfband filter see
(http://gnuradio.org/trac/wiki/UsrpFAQ/DDC).
To do so, the USRP (via GRC) should load the "std_4rx_0tx.rbf" image.
