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 sq

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 OF

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. ia

Hello sumit,
Thanks for your help i went through that document that you refered to, and i
tried to implement that OFDM transmitter part. This document only explain
about OFDM flow graph or transmitter. Is there any other document or

Hi All,
Does anyone know where we can change the Signal to noise ratio value in GNU
radio companion. i have made one DQPSK simulation for image transfer and now
i want to check the transmission and reception of the image at different SNR
values. I am unable to find any signal block where i can ch

I am trying to implement DQPSK implementation in GRC and trying to transfer

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 i
looking forward to hearfrom you. Thanks for ur help...
