Dear All,
I'm trying to perform a simple way of equalization in OFDM transmission. I
extracted the coefficients provided by the OFDM channel estimation block,
and sent them back to the transmitter using a TCP socket.
Are these coefficients valid to use in equalization, i.e., can I divide the

Dear All,
I've been trying to investigate how channel estimation works in OFDM based
on the implementation provided in Gnuradio for OFDM transmission. I found
that it was done in the block digital_ofdm_frame_acquisition.cc/h. As I
understand, the digital_ofdm_frame_acquisition::calculate_equalizer
Dear All,
I intend on implementing cooperative beamforming techniques using USRPs
(two USRPs send precoded versions of the same symbols to null out
transmission at certain directions). I need the two USRPs to be almost
perfectly synchronized in time and carrier frequency. What are the
available ti
Make sure you downloaded libboost libraries. Try the following in the
terminal
sudo apt-get install libboost1.48-all-dev
And rerun uhd_find_devices. If it doesn't work, try recompiling the UHD
driver after installing libboost, and then try uhd_find_devices

Dear all,
I've managed to install Gnuradio 3.2.2 on Ubuntu 12.04. And I installed the
BBN receiver (douggeiger branch). However, when I try to run the
bbn_80211_tx.py command, I get the following error:
karmo@karmolap:~/bbn_doug$ cd src/examples/
karmo@karmolap:~/bbn_doug/src/examples$ ./bbn_8021
Dear All,
I've been trying to install the BBN receiver on Gnuradio, and I've come to
the conclusion that it is inevitable to move back to older versions of
Gnuradio. So, I decided to install Gnuradio 3.2.2. on mu current
Ubuntu-12.04-running machine. However, there seems to be incompatibility

Hi all,
I'm fairly new to Gnuradio. I've been trying to install BBN receiver on
Gnuradio 3.6 and I've been getting errors of missing files like
"omnithread.h" and others. I'm not going to get into the details of the
issue here. I just want to ask those who were able to use it: Is it
possible to in
