摘要
目前认知无线电技术受到了极大的关注,其中的动态频谱分配问题是不得不面对的一个问题。讨论了动态频谱接入的分类,尤其是讨论了机会式频谱接入,包括其基本组成以及各组成部分的功能,并提出了实现这些功能的过程中遇到的挑战。将对今后动态频谱接入的进一步研究起到积极的促进作用。
Recently,the cognitive radio has been paid more attention,one of these problems is dynamic spectrum access.This paper discusses on the category of dynamic spectrum access,opportunistic spectrum access discussed especially,including basic components and their functions,and provides some challenges.It hopes that this paper can help the further and deeper research on dynamic spectrum access in the future.
