中文摘要：
认知无线网络是一种具有认知过程的网络,通过网络环境的学习分析,对网络状态进行规划、决策和响应.认知无线网络是解决网络容量受限问题的有效途径之一,满足了国家对频谱高效利用和异构网络融合的战略需求,作为5G关键技术为未来无线通信网络的发展指明方向.主要介绍认知无线网络的体系架构、研究的基础理论和实现的关键技术,最后给出认知无线网络的验证演示平台.
英文摘要：
Cognitive radio network （CRN） is a cognitive process of network,which makes planning,decision and response for network state through learning and analysis of the network environment.CRN is one of the effective ways to solve the limited network capacity,and to satisfy the national strategic demand on the frequency spectrum effficient-utilization and the integration of heterogeneous networks.As the key technology of 5G,CRN indicates the direction for the future development of wireless communication network.The system architecture for cognitive radio networks,the basic theory research,the key technologies of implementation were introduced,and the demonstration platform of CRN was presented.
