Performance Improvement Techniques For Radio Over Fiber System: An Overview

Abstract

Wireless Mobile Communication is entering into the era of 5G technology very rapidly. This increasing demand of Wireless communication is basically due to very simple installation and maintenance as compared to other wired network technologies. Therefore, rapidly increasing demand of broadband and high speed mobile communication requires a very high speed network which fulfills all the requirement of growing broadband wireless services. The only promising solution of the future wireless high speed mobile communication is transmission of Radio Frequency (RF) signals on optical fiber. This results a very high speed network called Radio over Fiber (RoF) Network which is basically a combination of wired network and wireless services in which RF signal is transmitted over the optical fiber by modulating the light with RF signal which contains the required information. ROF technology, now, becomes the backbone of the future broadband 5G wireless network. For ROF architecture, improvement in ROF link performance is the most challenging features. In this paper, an overview of ROF architecture is elaborated with various ROF link performance improvement techniques. The comparison in terms of advantage and limitation of every performance improvement technique is summarized. In the end, paper is concluded with the various research opportunities available for the consideration of researcher.
