Different SNR value - blockset

Hi,

I am trying to modify a simulink model in http://www.mathworks.nl/matlabcentral/fileexchange/3540 so that I can obtain a performance result of PER vs SNR. The problem is, I do not know how to form a loop so that the channel takes in different SNR value. Example: [0:30] dB

In general, you could use a For Each subsystem inside Simulink, or form loops using a MATLAB script and control the model from this script. In your case, I think the latter is the way to proceed.

Thank you very much Nirmal. I am not very familiar with Simulink, hence would you mind sharing on how do I do the latter?

I think i got it already!! thanks a lot
