| 摘 要： | 当前的频谱管理采用固定频谱分配策略,频谱资源被分配给固定的授权用户,从而造成了频谱资源的浪费。认知无线电技术是一种智能无线电通信技术,它能够大幅度提高系统的频谱利用率,有效解决目前的频谱资源匮乏问题。因此,认知无线电技术的出现必将对现有的频谱管理策略产生一定的影响。文中主要介绍了认知无线电的基本概念和频谱管理技术,并对认知无线电下的频谱管理提出了一些看法和建议。

| Abstract: | The current spectrum management adopts stationary spectrum allocation policy.The spectrum resources are allocated to the stationary authorized user,which leads to the waste of the spectrum resources.Cognitive Radio technology is an intelligent radio communication technology,which can greatly improve the system spectrum efficiency and resolve the problem of current deficiency of spectrum resources.Cognitive Radio technology will influence the policy of the current spectrum management.In this paper, the basic... |
