A novel low cost millimetre-wave over fiber (MMWoF) network based on Filter-bank multicarrier (FBMC) waveform with optical heterodyning technique is presented over 30-km standard single mode fiber (SSMF) as well as 10-m radio frequency (RF) wireless link. In the proposed scheme, five sub-bands FBMC signal of aggregated bit rate of 12 Gb/s to meet the demand for high data rate wireless connectivity and coherent heterodyning technique by beating two coherent optical tones without use of costly electronic components have been proposed for low phase noise 59.2 GHz millimeter wave (MMW) signal generation respectively. FBMC method is a promising option for 5G, which not only reduces out - of-band emissions but also overcomes the synchronization requirement of OFDM. A passively mode locked laser diode is used as a cost-efficient source since it exhibits a wide spectrum of equally spaced optical phase-locked modes and produce correlation of phase noise between the optical lines. High receiver sensitivity, small power penalty and very good spectra, low error vector magnitude (EVM) value, and excellent constellation diagrams in our proposed system make more authentic and stable with acceptable performance. Therefore, proposed MMWoF system could be the feasible solution for next -generation ubiquitous wireless network.
