认知无线电技术可以更有效地利用频谱资源,但是由于其允许多种无线技术共存与竞争,而多种无线技术对频谱资源的无序利用会降低其利用率。因此,该文提出了一种协作式频谱礼仪,其基本思想是认知用户之间共享有用信息,通过有用信息的共享来协调认知用户之间的行为,从而使认知用户能够协调对频谱资源的利用,同时在接入可用频谱资源时遵循一定的规则以避免相互间的碰撞。
Cognitive radio technology, which has proposed as a means to promote the efficient use of the spectrum, permits co-existence and competition of multiple radio technologies. However, out-of-order utilization of spectrum resources result in low overall efficiency. Therefore, the basic idea of a cooperative spectrum etiquette is proposed in this paper, The basic idea is that cognitive users of the spectrum intend to share the related information and coordinate the cognitive users depending on the sharing information. Thus, cognitive radio users can coordinate the utilization of spectrum resources and avoid the collision between users when cognitive radio users access available spectrum resource.声明:本文内容及配图由入驻作者撰写或者入驻合作网站授权转载。文章观点仅代表作者本人,不代表电子发烧友网立场。文章及其配图仅供工程师学习之用,如有内容侵权或者其他违规问题,请联系本站处理。 举报投诉
