I want to set up several Benchmark Tests for PowerPC Processors using
Altivec.
The MP-Scheduler Benchmark works for Core2 Duo and on PS3 (without Altivec)
fine.
But how can i set up the Benchmark for PowerPC Processors (e.g. Cell BE)
using the Altivec Extensions?
There are no options given to use
Thanks Matt, and Michael, for your input.
To clarify: I was thinking about a frequency offset detection at a later
stage in the demodulation process, which feeds back the frequency offset
to an initial xlating FIR filter (I do realise feeding back individual
samples is kind of ridiculous from a
i remember the gr-fsk4 demodulator uses the message queue to send frequency
correction info to a pre-demod freq-xlating filter.
Check out the code here maybe it will help

Hi,
I am doing linc transmitter by using gnu radio.In which i want to separate
OFDM signal in two constant envelope(software part) and then power amplify
it seprately, finally combine two signal(hardware part).I have done the
software part in Matlab and here is the code for that.
Hi,
I have finally compiled the uhd library. When I do sudo
./uhd_find_devices I get No UHD Devices Found. I have turned off the
firewall. I have loaded the firmware unto the SD card. When I turn on
the power of the USRP2 first all leds on the front are lit and then
only D is on.
I have no

Thanks for bringing that up, i should have sent the link as well:

How does the USRP2 get its IP address, how do you deal with multiple
USRP2 on the same
host? With IP routing, you'll generally need to have each

My program: usrp_wbfm_receive.grc was working fine. Now there seems to be a
problem with Ubuntu L
When I now run usrp_wbfm_receive.grc, I get the following error:

How do I find out what software is using the resource ??

I have a question about the thread safety of gr_wavfile_sink::close(). The
description says it is thread safe and it uses d_mutex, but what is to stop
the work() function from writing the file at the same time that close() (via
close_wav()) is writing and closing the file?
hello everyone,
I 'm trying to collect some samples from my spectrum sensing code running on
USRP2, which is a slightly revised version of 'usrp_spectrum_sense.py'. My
problem is that after some time during the scan of some band, this message

Well, the modification is for changing the code in such a way that it works
on USRP2 since the original version is written for USRP. The rest is the
same. Also it does't seem this is a programming bug since, it works for some
time and then it crashes.
