Hello Norzalina,
I understand that you're looking to create a graph of BER vs. SNR for ACO-OFDM program, as illustrated in the image you've provided.
I noticed a few typographical errors in the variable names within the code you shared:
- In the IFFT computation, the variable should be 'ACO_IFFT' instead of 'ACO_IFFT2' when calculating 'ACO_IFFT_P2S'. Here is the corrected segment:
% IFFT computation
ACO_IFFT = ifft(DataMat_ACO);
ACO_IFFT_P2S = ACO_IFFT.'; % corrected 'ACO_IFFT2' to 'ACO_IFFT'
- In the Zero Clipping section, the variable name should be 'CP_Part_ACO' rather than 'P_PART_ACO', as shown below:
% Zero Clipping
ZeroClip_ACO = ACO_IFFT_P2S;
for row = 1:m
for col = 1:N
if ACO_IFFT_P2S(row, col) < 0
ZeroClip_ACO(row, col) = 0;
end
end
end
CP_Part_ACO = ZeroClip_ACO(:, end - Ncp + 1:end); % corrected 'P_Part_ACO' to 'CP_Part_ACO'
CP_ACO = [CP_Part_ACO ZeroClip_ACO];
After implementing these changes, here is the resulting BER vs. SNR graph:
Hope this helps.
