I wasn’t able to open the file you had attached, Alistu. But I checked the file attached by Sam and file attached by me. I obtained the BER curve that are attached above from bot the files.
The signal is corrupted for BER analyzers 3 and 4 because I havent placed filter in them yet. I wanted to to first check the results for BER 1 and 2 before moving forward. Is this the reason, that I am not able to obtain the BER curve?
