Dear community,
I am trying to implement BPSK, QPSK and M-QAM on optisystem for radio over fiber.
I am able to see the constellation diagram upto 32-QAM on transmitter side(but only for 1 channel- with 60GHz and 10Gbits/sec as frequency and bit rate; cannot see good constellation diagram for the other channel). But I am unable to understand the layout and where exactly to place the constellation diagram visualiser on the receiver side.
I am attaching screenshot of the implemented circuits as well as .osd. Will really appreciate if anyone could suggest what parameters need to be changed or if there is an issue with the implemented circuit. Please help with the parameters for the bessel optical filter used as the receiver side.
Thanks in advance.
