摘要
本文归纳了从软件无线电到认知无线电功能的演进。认知无线电又是在软件无线电的基础上提出的智能化的无线通信技术,它着力解决频谱资源的有效利用问题;认知无线电概念的提出将对现行的频谱管理体制提出挑战,并给无线通信带来新的发展空间。在此基础上探讨了认知无线电技术未来发展值得关注的热点问题。
From software radio to cognition radio functional evolution the main body of a book has been summed up. Cognition radio is the technology communicating by letter in intellectualized wireless that the software brings forward on the radio basis, It makes effort to resolve frequency spectrum resource＇s having the effect makes use of question; Conceptual cognition radio put forward will bring forward challenge to frequency spectrum management system currently in effect, And bring new space for development to new space for development wireless communication. Have discussed the hot spot problem that cognition radio technology future development is worthy for to pay close attention to here on the basis.
