Hello sir,
Thank you for your worthy advice. As per your suggestion, I separated simulation projects for data 1 (NRZ), data 2 (DQPSK) and data 3 (PolSK) each transmitting at 40 Gbps datarate. After making some changes the individual projects are working as expected. The individual simulation projects are located in separate layouts in attached file.
Now when I tried to combine data 1 and data 2 (Layout 2 in the attached .osd file), the data 1 (NRZ) is received correctly but BER analyzer at receiver side of data 2 (DQPSK) shows Quality factor=0 dB. I have tried to locate the source of error, but couldn’t find one.
Sir it would be great help if you could look into it and suggest me the solution.
