[Discuss-gnuradio] What does the onboard FPGA now and how can I realtime process the signal?
Hi, I'm working with analyzing WLAN signals andplan to use the onboard FPGA to process the signal. I wonder what does this FPGA do by default? Is there any documents about this? What I need to do is before saving the IQ signal samples to files, do a correlation and time stamping on the incoming samples. Is this possible to do by the FPGA? I mean, can I feed the realtime stream to FPGA and process it? And if so, how? Is there some python functions which do this?

[Discuss-gnuradio] J. Cooley's 3-D waterfall display
All, Mr. Cooley wrote this code sometime early last year, and unfortunately something in the gnuradio or wxgui code has changed, and this code is no longer operable. The error I got in trying to run it with gnuradio 2.8 is: gnuradio_swig_python.py expects a std::vectorfloat,std::allocatorfloat I had an email exchange with Mr. Cooley, and he would like to fix his code, so any effort would be appreciated in that. And, as he said in our exchange, Now that I think about it, the waterfall Python OpenGL code that I did was based largely upon the similar wxgui-based fft. So, following the format of the wxgui versions may help lead you to the right functional calls, and get the right calls on the GnuRadio side. http://alumni.media.mit.edu/~jcooley/gr_experiments/experiments/fft_3d_time/gr_3d_fft_time.htm J.

The injection level of the RDS signal is typically around 1.5 to 2%, this is substantially less than the pilot, which is typically around 9%, but it should still be visible. Make sure you have a good signal without too much multipath. Also, you want to double-check whether the station you are looking at is indeed carrying RDS (not sure whether everybody does in Norway). If you end up writing a decoder, please drop me a line. The American version of RDS, called RBDS, is (of course) slightly different. I'd be interested in helping to making sure that it will work on both sides of the Atlantic.

Re: [Discuss-gnuradio] USRP Custom Filter Taps

The NTSC channel is 6 MHz wide so with these settings I get some interference from the adjacent channels. Is there a way to set the filter taps used by the USRP so that I could make a filter to remove the frequency infomation at the extreme right and left of the sampled data? I can use an FIR filter in the PYTHON runtime but it uses lots of CPU power. Yes, you can change the filter taps in the FPGA. See the halfband (HB) verilog code.

The end result being a stream from the USRP where 0 Hz is the center frequency of the audio carrier the the video carrier is at 4.5 MHz. Is this possible? The advantage here is that the baseband audio does not need to be shifted before fm demodulation; also the video carrier does not need to be shifted before demodulation (AM).

[Discuss-gnuradio] The Mystery Deepens: GNU Radio on Intel-Mac
* I can easily show on our brand new 20 Intel-iMac that a recent (Wednesday) SVN checkout of GNU Radio will compile, check, and install, but USB transport doesn't work. On a similarly equipped PPC-Mac, USB transport does function (albeit slowly in comparison, maybe 1/2 the speed, w/ the Intel-iMac maxing out at 32 M-Bytes/s - which is good news for those moving to Intel-Macs). * I can also show on the same computer that a compile on a MacBook Pro (MBP) dated (checked out on) July 13 does allow for USB transport. * GNU Radio uses dynamic libraries, and one of those is LIBUSB (for the USB transport), and the installed version of LIBUSB was just performed this week from version 0.1.12 - the same as what's installed on the MBP. * By changing a link in /usr from local_old (for the MBP compile from July 13) to local_new to the compile I did this week, the USB transport will either work or not (respectively). The facts thus far lead (past tense) me to believe that it was a change in GNU Radio's software. * I then retrieved an archive of the actual source code for the local_old install from the MBP and dropped it onto the Intel-iMac. I then made everything anew from that codebase (from July 13, which worked before) ... and ... drum roll please it DID NOT work! This now leads me to believe it was the change in XCode from 2.3 to 2.4 (released August 11, which would be about the time folk started noticing oddness). Since 2.3 is compatible with the Intel-Mac's, I will revert the install back to 2.3 to check out this theory (likely early next week). Yet even more as testing goes further. - MLD ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio

Yes, I could have used unix2dos but it seems to me that fixing the style for shell scripts isn't going to hurt anyone because *native* Windows tools aren't going to use them anyway. I think native Windows compilers can deal with unix style source files (though I'm not %100 certain of that), so they can be left as is.
