In this paper, we propose a novel hybrid fiber-wireless radio over fiber/ millimeter-wave (RoF/MMW) system using bidirectional amplify-and-forward (AF) relaying. Unlike conventional architecture, where only one type of transport media (e.g., copper, optical fiber, or wireless link) is used, both optical fiber and MMW wireless connection are employed in our proposal. We design the architecture of the...
In this paper, we have proposed a high-capacity backhaul network, which is based on mixed fiber-wireless systems using millimeter-wave radio-over-multi-core fiber (MMW RoMCF) and multiple-input multiple-output (MIMO) transmission, for next generation mobile access networks. In addition, we also investigate the use of avalanche photodiode (APD) to improve capacity of the proposed backhaul downlink...
All-optical two-way relaying is an advanced techniques that helps to improve the data-rate and throughput of free-space optical (FSO) communication systems. In this paper, we propose to implement all-optical two-way relaying in dual-hop FSO systems using network coding. The relay node that is based on optical regenerate-and-forward relaying is equipped with an all-optical XOR gate and optical hard-limiters...
In this paper, a novel two-way relaying technique based on network coding is proposed to improve the throughput of dual-hop mixed free-space optics (FSO)/radio-frequency (RF) communication systems. We investigate the performance of the proposed systems over Gamma-Gamma atmospheric turbulence and Rice/Rayleigh channels. The effect of pointing error on FSO link is also considered in our analysis. Closed-form...
In this paper, we investigate the performance of a millimeter-wave (MMW) radio-over-fiber (RoF) link, which is used to provide high data-rate and flexible connections in next-generation broadband optical-wireless access networks. The mixed optical fiber/wireless channel is assumed to be a dispersive and fading channel. Other physical layer impairments including noise and nonlinear distortion are also...
In this paper, we theoretically investigate the effects of noise and nonlinear distortion on the performance of orthogonal frequency-division multiplexing (OFDM) signal carried by millimeter-wave radio over fiber (RoF) systems. Various noise components are considered in this paper including shot noise, thermal noise and relative intensity noise. In addition, we take into account the effect of nonlinear...
