Hello,

I am simulating OFDM in Matlab to get a graph of BER vs SNR, however the problem is that the curve only shows the result till about 11 dB, even though I run the loop till 30dB


Is there any way I can get the full graph, even if the BER decreases with SNR or at maximum hits the noise, Matlab should still show, then why is this problem occurring?
 

Hello,

Its a problem of small number of OFDM symbols or small bit stream you are performing your simulation on.

In case of your virtual memory not capable of carrying larger streams so, you can run your curve over a larger number of runs to take average.
 
yes I observed that when the number of ofdm symbols were increased I got better results.

However, I have to show simulation at 64 subcarriers too. Increasing the data length has no affect
