An optical code-division multiple-access (OCDMA) network for radio-over-fiber (RoF) transmissions was proposed. The network encoders/decoders (codecs) were structured based on arrayed-waveguide-grating (AWG) routers coded using modified prime codes (MPCs). In the proposed system, the lower in-phase cross correlation could reduce the beating noise, and in the proposed study, its performance was ...

Recently, smart grid networks are researched and developed for the greening of the energy consumption. When introducing these into the university or the community, it is required not only the wide area cooperation and the high-speed monitoring & control, but also the construction of the heterogeneous infrastructure with the security and the flexibility. In this paper, recent research on the Rad...

The specific purpose paper was to design investigate RoF system based on mm-wave in order implement simple effective sys...

The optical orthogonal frequency division multiplexing (OFDM) is proven to be a most promising technology for the next-generation high-capacity and ultra-wide bandwidth 5G communication systems. 60 GHz millimeter-wave (mm-wave) band also becoming popular upcoming spectrum due today’s available dense used mobile, multimedia, data communication, etc. We propose system comprised of radio-over-fibe...

A plethora of enabling optical and wireless technologies have been emerging that can be used to build future-proof bimodal fiber-wireless (FiWi) broadband access networks. After overviewing key enabling radio-over-fiber (RoF) and radio-andfiber (R&F) technologies and briefly surveying the state of the art of FiWi networks, we introduce an Ethernet-based access-metro FiWi network, called SuperMA...

4×4 Multiple Input Output (MIMO) optical architecture based on Radio over Fiber (RoF) is proposed for 5G millimeter Wave (mmWave) indoor applications in the unlicensed 60 GHz band. First-order and second-order sidebands, generated by Dual-Drive Mach-Zehnder Modulator (DD-MZM), are exploited as subcarriers order to reduce number of Local Oscillators (LOs) implemented. Four MIMO-OFDM signals mult...

The objective of the research is to analyze, at simulation level, effect M-Quadrature Amplitude Modulation (M-QAM) technique, in downlink, for a converged Radio over Fiber (RoF) network infrastructure, implementing Ortho-gonal Frequency Division Multiplexing (OFDM) technique and Passive Optical Network architecture, with 10 Gbps capa-city (XG-PON). evaluation M-QAM modulation was done through p...

We describe some of our recent results on DWDM mm-wave radio-on-fiber (RoF) technology for future broadband wireless systems. A supercontinuum (SC) light source is a promising multiwavelength light source for the system with photonic up-conversion.

Wireless community these days debate frequently about convergence (next generation) network, a wireless system that is likely to appear after the successful deployment of the current third-generation (3G) systems. Towards convergence of various wireless networks, the integration of universal mobile telecommunication system (UMTS) and wireless local area network (WLAN) plays a major role. Enhanc...
