      The main problem seems to be again a sampling rate one. If you want to reproduce the 250 GHz signal your sampling rate at the minimum will have to be twice the largest frequency of your signal, that’s from the Nyquist sampling theorem

      I changed sampling rate in MSK to be Twice signal frequency as attached but i can’t obtained the result in this paper Figure3(c)RoF system using MSK technique

        Let me know if I am missing something, but I do not understand how the transmitters are supposed to function. In the paper they modulate a ~250 Gb/s carrier, but then they bandpass the frequency at 10 GHz. As far as I know there should not be any signal at that frequency, and so they are only transmitting noise. It doesn’t seem like a functioning transmitter design to me.
