Hi
I am trying from the past week to use the pre-cog library for data
transfer between two USRP N210 devices. I have tried a number of
configurations by replacing many blocks and modifying the Python code. I
managed to transmit just a single packet and then the transmitter stops
with no error.
E-mail me the flow graph you are using -> john.mals...@ettus.com

Hi all,
We have encountered an interesting problem in the clock_recovery_mm block
used in our BFSK system.
What happening is that, at lower data rates (i.e. at less than 54bps) we are
unable to decode the received data correctly,
however at higher data rates data is decoded fine.
What we are doi

This does not work. I am getting a "branch not found, building HEAD
instead" like error and then it builds 3.7. It looks as the gitbranch
part of the recipe really only works with branches while the version
numbers are tags. Does pybombs has a similar command than gitbranch to
define a tag in a rec

Hi, guys
Thanks in advance.
I plan to do a experiment in usrp that intentionally adding some
frequency offset in data symbol before transmission. Is that feasible
to implement it in gnuradio? Which block should I modify at sender
side?

Hi
I am trying to stream a VLC video stream to the gr-extras tuntap device.
I have modified the simple_trx demo to include tuntap device and run the
flow graph as a root. I assign the tap device the required ip address but I
am not sure how to assign a port number to it.
Then I configure the vl
Dear GNU Radio Guru,
For the sake of this list, I'm going to have to ask you to send all support
requests for pre-cog to john.malsb...@ettus.com. I'll be getting to the
other three e-mails you sent last night in a little while.

thanks for the suggestion. I already solved the problem here, by putting
this configure section in the recipe:
configure {
git checkout tags/v3.6.5.1
cmake .. -DCMAKE_BUILD_TYPE=$cmakebuildtype
-DCMAKE_INSTALL_PREFIX=$prefix $config_opt

Hi everyone,
I've finally started editing, cutting, and posting the videos from
last year's GRCon12 to Youtube. Only the presentations from day 1 of
the conference are live right now.
I will post individual links to each video on the conference website
under the Abstracts section:

Hello list, I would like to transmit some data using gnu-radio. My data
is a binary representation of an ASCII string.
I wrote my own block that builds the frame (header, payload, CRC,
trailer) as an array of 256 bytes (0s or 1s):
gr_make_io_signature(0, 0, 0)
gr_make_io_signature(1, 1, sizeo
Waqas,
U can use PFB_clock_sync instead of M&M. PFB_clock_sync implements the
maximum likelihood estimation algorithms, so using this block increasing
sps should not produce incorrect results.

>>1. Still I have to insert a "Packer Encoder" between my code and the
GMSK mod? If yes, with which parameters? The GMSK mod is configured with
Samples/Sym=50 , BT=0.4.
No. U can make custom packet structure and in that case u need not to use
Packet-Encoder.
