You can either use an FIR (see the filter section) or one of the

Well as you advice me, i set the --lo-offset=1M , for the following command
uhd_rx_cfile -a serial=4759a751 -N 10 -f 2.53G --samp-rate=2M
--lo-offset=1M noise.dat -v
However the peak is still there. I give below the output of
uhd_rx_cfile.py.
As you can see the Rx DDC frequency is

Omer,
This isn't a GNU Radio question. We don't really do Matlab support on this
mailing list. I'm sure there's some information about how to do this
elsewhere.

Probably I'll choose openCL. It means that I must learn a new language,but it's

Hey list,
I have created an OpenCL block that allows a user to interface with an
OpenCL compatible device, like a GPU. This block handles most of the
complications of using the OpenCL API. All the user has to do is feed
the block a .cl file with the kernel source and click run!
This block makes u
Hi all,
tomorrow, 16:00 CEST (1400 UTC), I will do an IRC session where I'll
answer questions for those of you applying to GSoC.
We'll meet in #gnuradio on Freenode.
There might be other mentors around, but it's me for sure.
If you upload your proposals until tomorrow morning my time, I might be

I am sending audio at 50 kHz sample rate via TCP sink from host A to other host

Hi Sajjad,
Ignore the last message! TCP Traceroute is actually what you are after:

Calculating delay is complex.
If you just want to know the average time between hosts on an IP network, then
use the Ping command. It has a RTT value in ms. Just remember that on a
packet switched network, this can vary but is typically under 1ms in a local
environment.
Similar delays exist

If you want to load files into Matlab which you saved for example through a
file sink, you can do that via the command fread. Check the documentation of
it. For the correspondences between Matlab and GNU Radio Type, compare the
fread documentation and this site of J.Blum:

I installed GnuRadio+UHD onto Ubuntu 12.10(64bit) and 13.04(64bit) by using
