Phase-Modulated Radio-over-Fiber Systems
Optical Fiber Communication Conference/National Fiber Optic Engineers Conference 2013, 2013We present an overview of phase-modulated RoF systems and review methods for downconversion based on phase-modulation. We describe a technique for phase-sensitive detection and demonstrate downconversion and I/Q channelization of a 64-QAM microwave signal.

Radio Over Fiber for Picocellular Network Architectures
Journal of Lightwave Technology, 2007We have studied RF transmission over various multimode fibers (MMFs) and a standard single-mode fiber, targeting picocellular networks for voice, data, and video applications. Bandwidth requirements of MMF links that are based on vertical-cavity surface-emitting laser (VCSEL) have been extensively studied.

5G radio over fiber for small-cells
2016 18th International Conference on Transparent Optical Networks (ICTON), 2016Demand for mobile networks with high capacity and increased data rates for the up-coming 5G scenarios will require a capillary presence of antennas and a tight coordination between macro-cells and small-cells. A new technique to distribute radio signals over fiber is presented.

Predistortion of Radio Over Fiber Links: Algorithms, Implementation, and Measurements
IEEE Transactions on Circuits and Systems I: Regular Papers, 2012Distributed antenna systems (DASs) have been proposed for use in high-data-rate wireless communications. Connecting the central unit to remote antenna units, radio over fiber (RoF) links become essential parts of the DAS. One of the major problems in the RoF links is the nonlinear distortion experienced in its optoelectronic devices.

Fronthaul links based on Analog Radio over Fiber [PDF]
2019 European Conference on Networks and Communications (EuCNC), 2019 Current Information and Communication Technology systems are nowadays close to a ‘capacity crunch’ as global IP traffic increases. This problem will be particularly important in the Mobile Fronthaul. This scenario is driving the search for new multiplexing techniques that could solve short-term bandwidth problems and provide a good scalability in the ...

Architectures and Algorithms for Radio-Over-Fiber Networks
Journal of Optical Communications and Networking, 2018To serve futuristic applications, wireless access with a wired-like connectivity is required. To accomplish this goal, we propose a design for a flexible radio-over-fiber (RoF) network, where we optimize the RoF network for the right choice of subcarrier modulation scheme.
