摘要 动态频谱接入技术对频谱实行动态管理,允许未授权用户在无干扰的情况下使用已授权用户的闲置频带,是解决现今无线频谱资源紧缺和利用率低等难题的有效途径,已成为无线通信领域的研究热点。本文介绍了动态频谱接入的侦测与避让方法,分析和讨论了各自的优缺点,并指出动态频谱接入需要进一步研究的问题和可能的发展方向。 Due to efficiently solve spectrum resource shortage and low spectrmn utilization rate problems, dynamic spectrum access has become a research focus. It can allow the unlicensed users to dynamically share the spectrum that is not used by the primary licensed users without interference by means of dynamic radio frequency spectrum management policy. This paper presents a comprehensive survey on the detecting and avoiding technology of dynamic spectrum access. Their primary virtues and deficiencies are also analyzed and discussed. Some problems worthy of further study and probably developing trends in the dynamic spectrum access field are presented.
