Radio over Fiber for Beyond 3G
2005 International Topical Meeting on Microwave Photonics, 2005This paper introduces radio over fiber (RoF) as one of enabling technologies of the fourth generation (4G) wireless communication. The RoF is a key technology to solve the problem about the high radio-wave propagation attenuation of 4G systems whose frequency band is expected to be higher than 3 GHz.

Radio-over-fiber technology and devices for 5G: an overview
SPIE Proceedings, 2016Radio-over-fiber has received renewed impetus due to various worldwide research initiatives in 5G. Here we will highlight recent developments at the device and integration level that are driving development of systems at various mmwave and sub-THz carriers, such as 30 GHz, 60 GHz and 120 GHz.

Software Defined Networking for cognitive Radio over Fiber systems
2016 IEEE Wireless Communications and Networking Conference Workshops (WCNCW), 2016In this paper a novel cognitive Radio over Fiber (RoF) system lined up with Software Defined Networking (SDN) requirements is presented. First, the SDN paradigm for the proposed hybrid RoF system with centralized topology is developed. Then, cognitive process enabling self-aware RoF network is outlined.

Radio over fiber systems [PDF]
The three main types of Radio Over Fiber (ROF)communication systems, namely analogue ROF, baseband ROF and digitized ROF are investigated. Optical fibers are increasingly replacing copper wires. In long-haul, high-bit-rate communication systems optical fiber has already become the dominant mode of transmission due to its enormous bandwidth and low loss.

Successive interference cancellation in the uplink of Radio-over-Fiber systems
Eurocon 2013, 2013Successive Interference Cancellation (SIC) is a well-known technique for enhancing wireless channel efficiency by allowing concurrent transmissions from multiple users. This multiuser detection technique is usually used in cellular systems. In this paper we adapt it to Radio-over-Fiber (RoF) system for the same purpose.

Analog and Digitized Radio-over-Fiber
2017Radio-over-Fiber (RoF) techniques aim to simplify as much as possible the configuration and the cost of the radio terminations of wireless networks. Both wireless LANs (WLAN) and cellular networks can potentially benefit from RoF. In wireless systems, the most costly equipment is the radio oscillators today necessary at each antenna site (called remote
