Flexible and Scalable Radio over Fiber Architecture [PDF]

Radioengineering, 2019
In this paper, we investigate a scalable Radio over Fiber (RoF) system compliant to 5G fronthauling requirements. The proposed RoF architecture is able to adjust the network resources and capacities to satisfy user demands in terms of service, data rate ...

Bidirectional Radio-Over-Fiber Systems Using Double-Clad Fibers for Optically Powered Remote Antenna Units

IEEE Photonics Journal, 2015
This paper shows and experimentally demonstrates bidirectional radio over fiber (RoF) using a double-clad fiber (DCF) for optically powered remote antenna units (RAUs).

PAPR对OFDM-ROF系统的性能影响分析

Guangtongxin yanjiu, 2010
文章在建立正交频分复用（OFDM）-光纤无线电（ROF）模型的基础上,获得了在外部强度调制下无寄生动态范围（SFDR）等性能指标的表达式,着重分析了射频信号平均功率对OFDM-ROF系统的影响,并与单载波ROF系统进行了比较。结果表明,系统设计时应尽量降低射频信号平均功率以获得更好的性能指标。在相同的射频信号功率下,较单载波ROF系统而言,OFDM-ROF系统的SFDR有5 dB左右的下降,系统设计时应采取措施降低OFDM-ROF系统的峰均功率比（PA-PR）。

Wideband Delta-Sigma Radio-Over-Fiber Embedding Complex-Valued Pulse-Distortion Model for 5G and Beyond

IEEE Access
We propose a wideband model-embedding delta-sigma radio-over-fiber (DS-RoF) design for keeping the adjacent channel leakage low. This RoF design is derived on the basis of the DS-RoF embedding a pulse-distortion model (PDM). To enable wideband modulation

ROF model on the graph

, 2014
In this paper we consider an analogue of the well-known in image processing, Rudin-Osher-Fatemi (ROF) denoising model on a general finite directed and connected graph. We consider the space BV on the graph and show that the unit ball of its dual space can be described as the image of the unit ball of the space ℓinfinity on the graph by a divergence ...

Early economic evaluation of the digital gait analysis system for fall prevention–Preliminary analysis of the GaitSmart system

Aging Medicine
Objective To develop an early economics evaluation (EEE) to assess the cost‐effectiveness of the GS in reducing the RoF and FoF. Methods A cost‐effectiveness analysis (CEA) with a return on investment (RoI) estimation was performed.
