update or sumthing on FPGA on usrp1 ???
Looking forward to hear from you.
Thanks for your help.
Cheers.

Hello all,
I am trying to transmitt and recieve OFDM signal Via USRP1 board. I made
basic simulation in GNU radio a signal source block and then interleave and
then OFDM modulator and then channel model block then usrp1 sink and fft
sink to see the output..In FFT sink at the end it shows proper
and i am using USRP1 board . i hope the above
too diagrams help you to understand my problem.
Thanks and Regards,

Don't forget the spaces (just copy paste should work)

Hello sumit,
I am trying to make OFDM trasmitter and reciever block diagram( with signal
processing blocks available in GNU Radio) in GNU Radio companion. As my
supervisor asked me to make simulation first in GNU radio software then move
on to USRP. i have made this basic simulation model for
for almost 12 hrs... so whts the situation
now.are you able to transmit and receive

Hi Sumit,
Thanks you so much for ur detailed explanation . i really appriciate your
help.
I am following the same steps as you mentioned earlier but iam getiing
this message when i
can change the bandwidth of the ofdm signal by changing the no of
occupied tones or fft length because bw = occupied tones/ fft length
let me know ur results.
Regards

hello sumit,
yah i have replaced the GMSK modulator and demodulator with OFDM
modulator and demaodulator
locate benchmark_ofdm_tx.py
The results will show you where the file is in your system.
Good luck,
Johnny

Hi Tom,
Thanks for your reply. yah i did use noise block and i am changing the
amplitude in the noise block but it does not make any difference in the
output. You said calculate the SNR value i have to check signal power and
determine the noise power. i dont know how to calculate those values.
And sorry to mention in the last mail that i will be suing USRP 1 .

Thank you so much Tom for your quick response.. yes i have found the code
scripts in gnurdio-examples/python/ofdm.
But iam not sure how to implement this code to make simulation in GNU radio.
could you please explain in bit detail how to use this code to make the
tranmission and reception blocks
looking forward to hearfrom you. Thanks for ur help...

Hi Everyone/Smith,
I am doin my M.Sc. project on OFDM Implementation in GNU RADIO (SDR) via
USRP.
I am quite new to GNU Radio i dont know much about its functions. I am
looking for benchmark_ofdm.py file that i can use to implement the design n
GNU radio and later on transmit and recieve via
in GNU Radio. I will really appriciate if
you kindly guide me how to make this simulation work. Thanks for your help
and for your valuable information. looking forward to hear from you.
Regards,
Waqas.
