Hi Patil,
To create a subsystem, you just need to select its all component and by right-click just choose “Create Subsystem”
To check the subsystem components just double click on it, then another subsystem window will open having the subsystem elements.Hope that helps,

Hi Patil,
I will try to check your file, but in the mean time try to trace the signal from one point to another to catch the position where the signal disappear.Mohamed Abouseif

Hi Patil,
I check you program,
please check “Show Eye Diagram” on right of the BER Analyzer.
I did and could see some data (not sure correct or not but there are numbers). Then try to modify you system according to your needs.thanks

yeah, I already checked that. It is not giving Min-BER as expected.

so you need to adapt your system parameter, I think It is a design issue.
thanks

Design parameters are very similar to that given on optiwave video. Also, I referred some papers they have same parameters.
