There's the DVB-T transmitter and receiver in the Digital Television
component of GNU Radio. It's capable of 31.6 Mbps in a standard 8 MHz
bandwidth. (and can be used at higher bandwidths).
I have some OOT modules that allow sending IP packets over DVB. Note
that these modules only implement t
Hi,
For OFDM transmitter and receiver, I was using benchmark_tx/rx
implementations. However, I am wondering what is the best publicly
available OFDM implementation for relatively high bandwidths (10s of MHz)
and data rates (10s of Mbps)?
Best,
Sinan

I am trying to find channel coff. through ofdm implementaion. I added and
edited the ofdm frame acquisition block and set verbose to 1. I get wrong
cooff. so i think added wrong blocks, can anyone help me with blocks to
add.

Hi everyone,
I am trying to test signal tranmit by using OFDM modulator via USRP1 and i
am getting this error message . Does anyone know what does it mean?or how to
fix this problem. i connected one usrp1 with usb cable to my laptop just to
check the transmission. it shows the signal in FFT sink

Hey Marcus this was very very informative.This offset was really killing me
every time when I was running the OFDM example.I think I need to order some

Hello sumit,
I am trying to make OFDM trasmitter and reciever block diagram( with signal

supervisor asked me to make simulation first in GNU radio software then move
on to USRP. i have made this basic simulation model for OF

Thanks Johnny yah that worked ..it is showing me different options for
OFDM... so for this particular benchmark_ofdm file the signal processing
blocks are displaying in GNU Radio companion or is there anything else i
have to do to make the block diagram of the system? thank you so much for
your q

Yes johnny for a while i need only OFDM transmitter and reciever via USRP
for my project. I just want that this OFDM system can transmit and receive
via USRP, that is my aim at the moment.
Thanks once again for your detailed clarification. i will try that and let
you know the results.
Thank yo
Thanks johnny for your response yes i am quite new to GNU Radio so just
started to learn about this software.
Ok i will play with it and let you know the results.
Thanks for your help guys..

You seem to be quite new to Linux, what do you intend to do for your Master
thesis? Gnuradio is not something you can master in a couple of months.
To go to a directory, you need to use the 'cd' command. Ie
cd /usr/local/bin
My benchmark_ofdm code is not in /usr/local/bin so when you get to that

there u will find benchmark files for ofdm (both transmission and reception)
u need to type benchmark_ofdm_rx.py -h
and benchmark_ofdm_tx.py -h
these will show you the parameters u can play with.
after that u can run these files by typing ./benchmark_ofdm_tx.py

benchmark programs are quite good to start with...
u can type benchmark_ofdm.py -h to see all the parameters u can play

Hello All,
Does anyone know how to implement OFDM implementation by USING GNU RADIO
COMPANION. Some one told me to use Benchmark_OFDM.py script. But i am not
sure how this will work and how we can put this script in GNU radio
companion to make the simulation. If any one know please guide me . i
Hi,
I want to implement OFDM on gnu radio platform.
Is it possible to simulate the code provided without using the hardware .
Ben told me to use the Benchmark ofdm code. I wanted to know whether there
is some documentation for it or not.
Thanking you
