SDN based millimetre wave radio over fiber (RoF) network

SPIE Proceedings, 2015
This paper introduces software-defined, millimeter Wave (mm-Wave) networks with Radio over Fiber (RoF) for the delivery of gigabit connectivity required to develop fifth generation (5G) mobile. This network will enable an effective open access system allowing providers to manage and lease the infrastructure to service providers through unbundling new ...

Digital predistortion of radio over fiber (RoF) link using hybrid Memetic algorithm

Journal of Optical Communications, 2021
Abstract Despite their many advantages over other communication links, radio over fiber (RoF) links also suffer from nonlinearity. This limits the dynamic range performance of the RoF link. Linearization techniques like digital predistortion can be explored for mitigating this nonlinearity.

Study on performance of Digitized Radio over Fiber (RoF) system using EDFA and Coherent receiver

The 2013 RIVF International Conference on Computing & Communication Technologies - Research, Innovation, and Vision for Future (RIVF), 2013
In this paper, a calculating model of Digitized Radio over Fiber (RoF) system using EDFA amplifier and Coherent receiver is proposed. We then investigate Signal-to-Noise Ratio (SNR) in different parts of the system and establish SNRtotal equation at the output of RF signal recovery in three cases: Direct Detection, Coherent Detection and Combined EDFA ...

Survivability models for radio-over-fiber passive optical networks (RoF-PON)/PON

2011 seventh International Computer Engineering Conference (ICENCO'2011), 2011
In this paper, we will propose some models for PON/RoF-PON combines a number of ideas used before in the research papers, the ITU-U recommendations and also a number of novel models. We compare between those proposed models by using the Expected Survivability Function; a simple and intelligent tool to evaluate network survivability.
