Fwd: How can I add freq. offset(related to time index) after IFFT in data symbol in ofdm example?

for index = 1:PacketLength
PacketWithFreqOffset(index) =
Packet(index)exp(i2piSampleRateindex);
end

So is above implementation in matlab similar to that in Gnuradio?

No. GNURadio implementation resembles Simulink instead of Matlab. Just
think how can u add freq-offset in Simulink and replicate that in
GNURadio

Thanks again. I am not familiar with simulink. U mean we can visually
program in GR using signal Block or widget instead of writing all code
directly?
Yes
