3.2 RF based RoF system
In, our system instead of IF we are now modulating RF with
an optical signal. Four RF signals used in our design are 15
GHz, 30 GHz, 45 GHz and 75 GHz. The system design is
same as IFoF only instead of IF, RF signals are used as shown
in figure 3.2. BER, Q-factor and power values of RF signals
obtained at the receiver are tabulated in below table 2.
