Hi Sara,
although that guide is correct (it just uses the popular and
well-working build-gnuradio script), I'm always a little surprised
where people find information. For later reference: The official GNU

Hi everyone,
Sorry for the short notice, but there will be no Dev Call today. With the
hackfest, WSR and the recent release, we've been discussing a lot of things
all the time, and don't really have important stuff lined up for this call.
Cheers,

Hi George,
practical implementation aside: Thanks to Parseval's theorem, looking
at relative signal strength in frequency and time domain is equivalent.
You can just use a number sink or time sink with a low pass filter to

One thing that I forgot to mention is that VOLK is written purely in
C, so C++ vectors as-is won't work. You need to index them, but
luckily, std::vector's are guaranteed to be contiguous in memory whe

No, but it would be nice to have a kernel for that.

Well you could implement your Matrix inversion using VOLK, of course.

Hi all,
I am using ubuntu 13.04, GNUradio 3.7.
I have a question related to VOLK library.
When I create a vector, lets say:
vector y1;
Can I multiply this vector to another vector using VOLK?
Is there any good documentation for this?

Hi Aditya,
Thanks for your reply. Today I got the chance to measure the lower samplerates
and here are the results:
I measured the writingspeed on disk and the number of the "O"s for 1 minute
runtime. Running X and iotop in the back has nearly no impact.
MHz Mb/s"O"-count
32 310
A good way to test is to use the hier blocks for OFDM (you still need to
reduce amplitude), they will set up everything in a way that will work
for sure. See the loopback example in gr-digital/examples/ofdm.
