Hello,
I have a question in bit truncation.
Say I have a 14-bit FM waveform, digitized. Underneath that signal
assuming they are both in the same frequency, there is another signal say
an AM signal. The difference between the two is about 40 dB. Is there way
such that I can remove the AM sig

2.5 ppm. Datasheet may not be ready for a week or two.

Hi Everyone,
I am running custom FPGA firmware for a low latency control system on
a USRP1. Presently I am using a variant of the usrper.cc tool for
loading firmware and control of command registers in the FPGA. I need
to be able to stream data over USB into a file or other application
but this
A sane fix:

Hi Matt,
just wondering what the PPM spec is of the onboard TCXO? Will the datasheet
be available soon?
Thanks

On machines where sizeof(long) = sizeof(int) the code for calculating
scale factors produced an overflow warning. This change simplifies the
code by eliminating the shift. The compiler should calculate the constant
at compile time anyway.

Here is a proposed fix for a compile warning on 32 bit machines. I am
interested in feedback on how I replace the shift with 2^(NBITS-1). I
don't see any reason to keep teh shift, since the compiler should do the
math at compile time. I am a little worried about the NBITS=32
Hi Ryan,
Thanks very much for your answer! You mean you are inetersted in
developing a stand alone receiver "with" the USRP?
I'm sorry, what do you mean by performance metrics?
thanks again,
Walter

Hi Walter,
My group is using the USRP to record raw RF data at GPS and GLONASS
frequencies. We do all of our signal processing in post right now, but are
interested in developing a stand alone receiver. If you search the mailing
list you'll find some other folks who are implementing GPS receiver

Michael,
Good description of the TPB running mechanism!
Here is a more detailed explanation with some graph illustrations (see

Josh,
Thanks for posting your work on stream tag.
I'd like to try out your code. Would you please tell me which version of
GNU Radio to use with your code examples? Any other specific requirements?
I will let you know what I will get.
Thanks,
Andrew

hi,
i was wondering whether the usrp can be used as a "gps receiver". if so,
1) how can i achieve this?
2) any link you could provide for me to read?
3) what daughterboards should be used?
4) Can the usrp be used with OpenGTS (for example) for tracking (usrp as
a gps receiver)?
thanks in adv
