In order to meet the ever increasing demand for larger transmission bandwidth, Wireless network based on radio-over-fiber technologies is a very beneficial solution. Various disadvantages of Analog Radio over Fiber link such as non-linearity, chromatic Dispersion can be mitigated by use of Digital Radio over Fiber link. A digitized RF-over-Fiber transmission scheme based on Bandpass Sampling th...

The massive growth of wireless traffic goes hand in with the deployment advanced radio interfaces as well network densification. This has a direct impact on access architecture, which today is moving from centralized to distributed deployments through use large number points (APs). paper verifies feasibility deploying multiple APs series single line ring topology cell-less network. On one hand,...

Radio over fibre (RoF) techniques [1] have been researched from many years and although there are numerous deployments world-wide, the technology is still to have a major impact on mainstream wireless and cellular networks [2]. To date the offerings of the major vendors such as Andrew, ADC and Zinwave, have focused on what are essentially distributed antenna systems. However, as this paper will...

This thesis is devoted to the study of mathematical properties of exact minimizers for the K–,L–, and E– functionals of the theory of real interpolation. Recently exact minimizers for these functionals have appeared in important results in image processing. In the thesis, we present a geometry of optimal decomposition for L– functional for the couple (`2, X), where space `2 is defined by the st...

This is an extended and updated version of the invited paper given at the International Topical Meeting on Microwave Photonics, 2002 (MWP2002), in which current and emerging radio over fiber technologies for cellular communications applications were described. INTRODUCTION Radio over fiber has recently emerged as a useful technology for providing specialized coverage of wireless communications ...

The ubiquitous deployment of 5G systems is expected shortly. 5th generation are envisioned to deliver a comprehensive selection services with revolutionary data rates through single network. Optical fiber networks going be the backbone such endowing huge transfers. Radio over Fiber (RoF) promising network architecture that can provide all provisions envisaged in development systems. However, ce...

Wavelength conversion has been suggested as one of the key functions for wavelengthdivision-multiplexing (WDM) optical networks and photonic switch blocks. Several methods, such as a self-phase modulation (SPM), a cross-gain modulation (XGM), and crossphase modulation (XPM), can be used to realize all optical wavelength conversion (AOWC) [1-29]. However, four-wave mixing (FWM) based on nonlinea...

Bandwidth hungry services are developing rapidly in home networking and needs for Gigabit Home Networks will appear shortly, following the introduction of Gigabit optical access networks. In addition, ubiquitous wireless connectivity is required by users to connect multiple multimedia devices inside the home. Some wireless standards, such as Ultra Wide Band (UWB), are able to provide Gbit/s dat...

The increase in internet traffic, number of users, and availability of mobile devices poses a challenge to wireless technologies. In long-term evolution (LTE) advanced system, heterogeneous networks (HetNet) using centralized coordinated multipoint (CoMP) transmitting radio over optical fibers (LTE A-ROF) have provided a feasible way of satisfying user demands. In this paper, an orthogonal wave...
