Hello all....
Plz I need help about simulation of the effect of CFO in the received symbols in OFDM.. the MATLAB Simulation of the Picture I apploaded..
I need it Urgently.. Plz


 

This picture is from book MIMO-OFDM Wireless Communications with Matlab by Cho Y.S. The MATLAB code is located in book directly below the figure.

function y_CFO=add_CFO(y,CFO,Nfft)
% add CFO (carrier frequency offset)
% y : Received signal
% CFO = IFO (integral CFO) + FFO (fractional CFO)
% Nfft = FFT size
nn=0:length-1; y_CFO = y.*exp(j*2*pi*CFO*nn/Nfft); % Eq.(5.7)

I'm sorry if I misunderstood you.
 

I understand!! but how the PLOT can be obtained sir, @ zemtcov (I'm sorry, I'm very new in using MATLAB, so I need some explanation)
 

Hi,,,,
I didn't get a helpful answer, so again I'm requesting a help about a complete MATLAB Code for the received symbols subject to CFOs.. plz help me, I need it urgently.
