Abstract

An optical-wireless communication (OWC) model with the generation 60 GHz millimeter wave (mm-wave) is discussed and investigated. This system is proposed to transfer a digital signal with a 320 Mbps data rate by using an optical signal over a wireless channel as a part of visible light communication (VLC) in the fifth generation (5G) for small cell networks. The electrical generation domain has a challenging with the mm-wave; therefore, our model is introduced and examined. The mm-wave and phase modulation are proposed in the optical wireless communication for the first time. OWC system with 320 Mbps signal transmission is successfully achieved. In our simulation, the directly modulated laser (DML) is driven by the digital signal; then, the generated optical signal is mixed by the phase modulator with 60 GHz mm-wave carrier to result in a phase modulated optical signal to be transmitted over the wireless channel. Based on the simulation results, the proposed OWC system is successfully working to transfer a 320 Mbps data rate over 10m wireless channel distance with low BER (10-5) and good Q-Factor (4). The simulation results show that a cost-effective operation with mm-wave for faster transmission. This research ensures a possible optical link with low cost and RF interference.
