Hello everyone. I am getting confuse of the Radio over Fiber SCM-ASK from the Optisystem samples. The component like amplitude modulator, bpf bessel, and amplitude demodulator is given 1.7 GHz at the frequency. But the carrier generator is just 49.25 MHz, and it is too far if compared by the modulated signal at 1.7 GHz (if im not mistaken). By far I know, the carrier should be higher than the modulated signal (information) itself. I need explanation here for this RoF SCM-ASK, why the parameter should be like that or so.
Thank you very much..
