I've noticed a disquieting, nay, alarming, trend on this mailing list in
the last year or so.
Software Defined Radio has become cool, it has become the chic thing
to do in graduate school, or
as the foundation for the start up of a new business. Everybody wants
to do it.

In my time here, I've learned that SDRs bring together two worlds... those
in EE, and those in CS. Those from the CS world don't understand a lot of
the RF world, but would like to leverage SDRs to achieve something at the
higher level and are thrown in to the RF world. Those in the EE world,

Your sentiments are understandable. I know the feeling. But please allow me
to give an a different perspective.

Hi all,
Has anyone out there implemented discontinuous OFDM on GNU Radio and the
USRP? I've seen a couple papers with an implementation on GNU Radio in
DySPAN and some other conferences, but nobody has responded to my requests
for the implementation.

Hi All;
My Gnuradio development system just had a major brain fart, so I'm looking
for recommendations on a replacement system.
I know there are a number of flavors of quad core system out there but some
appear to be better than others for this application.
From what I have observed,
Can someone give me an idea on how i can put some kind of visual markers on
a fft graph? attached is a photoshop image of what i would like to
accomplish. Any ideas on how i could go about doing this?

From what I have found so far, it seems that the i7 920 is only available in
desktop systems. The leading edge in laptops seems to be the i7-720
processor.
I could always develop on a desktop and then port the software to a laptop
later, when prices come down J

G'day William,
FYI: About a week ago, I was facing the same situation and decided to purchase
a Dell Studio XPS 1645 laptop. The major factors for my decision were
1.) Onsite warranty repair
2.) Better screen resolution 1080p (1920x1080)
3.) Free inclusion of a blue-ray player (special)
4.)
Hi, everyone
I'm confusing with the function set_gain().I got the gain range by function
gain_range(),the first value is 0dB, the second is 90dB, and step is 0.05, the
gain is from daughter board, or include the gain from ADC? Anyone can expain
the details?

Hi all,
I have problem using two daughter boards one as transceiver and the other
for sensing.
The process is ok, decimation rate is 256, freq: 2.4 - 2.5 GHz
but there is a shift in the sensed frequencies.
I read 'FSK with RFX2400' it explained about it, however when i use only one
board for
Do you mean discontinuous in time or frequency? If you're talking
about frequency (selectively turning off subcarriers, which I've heard
referred to as non-contiguous OFDM mostly), then there are definitely
a few implementations out there. I saw two groups at the latest IEEE
DySPAN
G'day,
I've created a simple application in GRC using a TCP source in server mode.
When started, it excepts connections on the allocated port for the first time.
However, after statefully disconnecting from the port, any further attempts to
make a new connection with the server application
Yes, definitely expected because of the way things are implemented:
The server block waits on listen, and passes the file descriptor to the
first connection to the gnuradio file descriptor source/sink. After that
there is no way for it to accept another connection and replace the file
Hello Everyone,
I've made a basic DBPSK transmitter and receiver. I can receive ASCII
strings fine and the spectrum looks exactly as it should.
However, if I swap the DBPSK modulator/demodulator for the DQPSK
modulator/demodulator, my system breaks. I can no longer receive the same
strings
