This paper reports an end-to-end demonstration of a fiber-wireless mobile fronthaul (MFH) network based on hybrid intermediate-frequency-over-fiber (IFoF) and radio-over-fiber (RoF) links using 28-GHz millimeter-wave (MMW) band. We successfully transmitted 24 64-QAM OFDM signals with total bandwidth 9.12 GHz over 20-km broadband IFoF, 1-km narrowband 500-m RoF, 10-m free-space aggregate capacit...

Radio over Fiber (RoF) Technology is integration of radio emission in optical fibre transmission at intervals network infrastructures that's thought of to be cost-efficient, sensible and comparatively versatile system configuration for long-haul transport wireless signals.

Providing high data rates and wide bandwidth applications are the most important challenges that mobile systems and radio networks are trying to accomplish. Radio over Fiber (RoF) system is a promoting research field since it benefits of Passive Optical Network (PON) advantages and unlicensed large bands in 60 GHz millimeter band (57-64GHz). In this study, we consider a complete downlink RoF sy...

In this paper, the performance of radio-over-fiber (RoF) links employing intensity modulation has been investigated in terms of signal to noise ratio (SNR). An analytical model including dispersion, laser and radio frequency (RF) oscillator phase noise is constructed to estimate the SNR performance for 64quadrature amplitude modulation (QAM) based RoF systems. It has been observed that the RF o...

A carrier phase-shifted (CPS) double sideband (DSB) modulation technique in radio-over-fiber (RoF) system is proposed and experimentally demonstrated. By tuning the biases in a single-drive dual parallel Mach-Zehnder modulator (SD-DPMZM), the optical carrier in the DSB spectrum acquires additional phase shift. The transmittance response of a dispersive RoF link is thus being controlled and shif...

Radio over Fiber refers to a technology whereby light is modulated by a radio signal and transmitted over an optical fiber link to facilitate wireless access. In RoF system, wireless signals are transported in optical form between a central station and a set of base stations before being radiated through the air. Each base station is adapted to communicate over a radio link with at least one us...

This paper reviews optical coherent technologies in next generation access networks with the use of radio over fiber (RoF), which offer key enabling technologies of wired and wireless integrated and/or converged broadband access networks to accommodate rapidly widespread cloud computing services. We describe technical issues on conventional RoF based on subcarrier modulation (SCM) and their cou...

Hybrid Analog and Digital Access Networks Architectures for Fixed/Mobile Infrastructure Convergence In order to realize the convergence of the optical infrastructure of fixed and mobile access networks, the objective of this thesis is to study the solutions for distributing native radio carriers through typical optical access networks.

A radio over fiber (RoF) system is a kind of analog optical transmission system and considered as a strong candidate for the next-generation fronthaul link in the future mobile network. In RoF systems, nonlinearity compensation is essential to increase the link capacity. In this paper, we propose a nonlinearity detection and compensation scheme using a monitoring channel in RoF systems. A monit...
