Optical impairments mitigation in millimeter-wave fiber-wireless systems

Abstract

Hybrid fiber-wireless networks for fixed wireless access operating in the millimeter-wave wave (mm-wave) frequency region have been actively pursued to provide untethered connectivity to ultra-high bandwidth communications. The architecture of such radio networks requires a large number of antenna base stations with high throughput to be deployed to maximize the geographical coverage with main switching and routing functionalities located in a centralized location. The transportation of mm-wave wireless signals within the hybrid network is subject to low opto-electronic conversion efficiency, fiber chromatic dispersion and also signal degradation due to nonlinearity along the link. One of th..
