摘　　要：随着各种各样无线应用的增加,频谱资源日趋紧张。认知无线电基于对无线通信环境的感知、规划、决策和调度,可采用动态频谱接入等方式以有效地提高授权频段的利用率,认知无线电开发平台对其相关技术的研发至关重要。介绍了典型认知节点的结构框架、部分硬件开发平台及其相关软件开发环境,给出了4种国外基于认知无线电的网络化测试平台的构成及特性,展望了可应用无线认知平台的未来研究领域。As more and more wireless applications emerge,spectrum resources become increasingly overcrowded. Based on the perception,planning,decision- making and scheduling of the wireless communication environment,cognitive radio（ CR） can effectively improve the utilization of licensed spectrum through dynamic spectrum access. The cognitive radio development platforms are of great significance to the relevant technologies. The paper introduces the typical framework of cognitive node,hardware platforms and the related software development environment. Then,the constitutions and properties of four CR- based networking test beds of foreign countries are given. Furthermore,the application prospects of CR platforms are presented.
