"Privacy in residential applications is a d

Have you looked at this paper?
http://wsl.stanford.edu/~ee359/doppler2.pdf
I had seen this before, but thanks anyway.
I'll follow-up to this group once I'm getting anywhere with my code.

sorry, my mistake. This should read: ... the negated sum of the phase shift

a copy somewhere?
I am not really interested in the receiver code, but in the apparently included
code to generate (simulate) a GPS signal.
Thanks in advance,

.
Right now I unfortunately simply don't have the time to research/investigate
this further :/
However, if you do get a working example script or grc graph at some point,
please make the effort of publishing/posting it so it can be referenced by
others.

for gnuradio. The biggest challenge is the analog frontend because of
the 80dB difference between Tx and Rx. you will probably need two
antennas, and switch off / attenuate the Rx path while transmitting.
If you have any questions, just ping me.

first results of this work are already merged in recent 2.6.x mainline
kernels).
Harald, in what way is your experience different?
Hope my email clarifies :)

on the 1394 bus, and the linux dv1394 driver provides a mmap() interface
for receive and send from/to userspace programs.
just my two (euro-)cents ;)

I was also thinking of speeding up the USB data transfers by using a

experiment with creating frontends for them.
So to start lazy, I would try basing my frontend on the TVRX schematics
:)

btw: My first project for the USRP will be passive sniffing of
ISO14443 A/B (the on-the-air protocol used between rfid readers and tags

::pending_remove: failed

So it seems like the REAPURB ioctl returns a NULL-pointer and aborts.
Does anyone have an idea what's going on?
