摘　　要：认知无线电与认知无线网络的明显区别之一是认知环境发生了变化,从无线环境拓展到网络环境与用户环境。从认知无线电到认知无线网络的演进过程中,为了深入研究环境认知的基础理论,在分析认知网络的基本概念和工作机理的基础上,提出了多域认知的思想,构建了一个包括多域本地认知层、多域协同认知层和多域主动认知层的3层认知理论体系框架,提出了基于认知引擎的多域认知实现框架,探讨了多域认知的研究内容,为认知无线网络的应用奠定了基础。Environment cognition is the most distinct difference between cognitive radio and cognitive radio networks, and environment cognition extends from wireless environment to network environment and user environment. During the evolution from cognitive radio to cognitive radio networks, in order to investigate deeply on basic theories of environment cognition, the cognitive ability of wireless networks and the basic concept of cognitive network were studied. The concept of multi-domain cognition and mechanism of cognitive networks were proposed. Under the framework of cognitive theory, multi-domain cognition was divided into three layers, which were local multi-domain cognition, cooperative multi-domain cognition and initiative multi-domain cognition respectively. The framework of multi-domain cognition based on cognitive engine was described. Finally, investigations and basic theories on multi-domain cognition were presented. Those research results lay a foundation for the application of cognitive radio networks.
