Nyquist QAM optical transmitter
Dear all,
I am trying to build a QAM optical transmitter different from the default in Optisystem. The difference consists in using a raised cosine M-ary pulse generator with small roll-off factor (close to Nyquist pulse shaping) instead of a square signal shape M-ary pulse generator. The help of the optical QAM optical transmitter has an example on how to build the optical QAM transmitter using optisystem components (such as M-ary pulse generator for example), however it does not mention the parameters of the LiNb Mach-Zehnder Modulator component . I tried several parameters however i was not successful in building a QAM signal. Can anyone help?
