摘要

本文讨论了认知无线电(CR)的基本概念，并研究了超宽带(UWB)技术作为实现认知无线电系统的使能传输技术之一。首先，我们提出了一种分析方法来评估窄带(NB)和超宽带通信系统在现实场景中的干扰影响和共存问题。然后，基于这种方法，我们展示了UWB技术在调整传输频谱以抵消NB干扰，同时保证现有窄带通信的低频谱发射方面的巨大潜力

Coexistence Issues in Cognitive Radios Based on Ultra-Wide Bandwidth Systems

In this paper we discuss the basic concepts underlying cognitive radio (CR) and investigate the ultra wide bandwidth (UWB) technology as one of the enabling transmission techniques for the implementation of CR systems. Firstly, we propose an analytical methodology to assess the interference impact and coexistence issues between narrowband (NB) and UWB communication systems in a realistic scenario. Then, based on this methodology we show the great potential of the UWB technology in adapting the transmitted spectrum to counteract NB interference and at the same time to guarantee low spectral emissions over existing narrowband communications
