Modeling and simulation of OFDM scheme for radio over fiber (RoF)

2015 2nd International Conference on Information Technology, Computer, and Electrical Engineering (ICITACEE), 2015
Radio over fiber (RoF) system is the most appropriate combination of fiber optic link and radio waves. Orthogonal frequency division multiplexing (OFDM)-RoF system can increase the capacity of modulation radio frequency (RF) access with high speed data transmission.

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.

Radio over Fiber (RoF): A comparison of low-cost systems

2013
In order to assess the potential of low-cost radio-over-fiber (RoF) solutions, in this paper we make a comparison of three full-duplex RoF systems. These systems are low-cost solutions that use remote modulation, with a single centralized light source used at the central station to generate a downlink wavelength that is reused at the remote location ...

Modeling of Radio over Fiber (RoF) system incorporating multi-carrier multiplexing

2016 International Conference on Computing, Communication and Automation (ICCCA), 2016
Radio over Fiber system is a promising technology to fulfill elevated demand of capacity and high data rate. The performance of RoF system is severely degraded due to presence of nonlinear distortions for instance inter-modulation distortion and harmonic distortion. Accordingly, orthogonal frequency division multiplexing (OFDM) scheme is being proposed

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.
