HELLO SHANMUGA SRINIVASAN
I tried to open ur osd file but i could not understand the flow of ur system design and i got confused many a times..i could see that you have kept MUX bandwidth equal to 50 GHz.. you need to do same for DEMUX..i would personally suggest you to to change other parameters like power , bits per sample, increase the sequence length which is very important…also keep the symbol rate larger than your global bit rate..keep it atleast 0.5 times higher than the bit rate and c how ur system works for that..i hope it is helpful to u…
thanks and regards
