Experimentation Methodology of Orthogonal Frequency Division Multiplexing Signals Process using Radio over Fiber (RoF) system

Current and future trends in broadband communication, particularly for 5G mobile applications, will include Orthogonal Frequency Division Multiplexing (OFDM) into Radio over Fiber (RoF) technology. Its resistance to multipath fading and spectrum efficiency have made Orthogonal Frequency Division Multiplexing a well-known technique. Network spectrum efficiency has been achieved using the modulation format in optical and wireless communication systems. After that, a system was proposed in which four 18Gbps QAM (Quadrature Amplitude Modulation) signals were generated in each transmitter and modulated in continuous wave (CW) using Mach Zehnder Modulator (MZM) before being transmitted over Single Mode Fiber (SMF), which performs significantly high data rates and is cost-effective in accordance with the results modelled.
