摘　　要： 认知无线电是被公认的解决移动无线网络频谱资源短缺和频谱资源动态分配问题的最有效和最有潜力的技术。基于认知无线电技术目前在移动无线网络中的实际应用情况,详细分析了认知无线网络目前所存在的无线频谱资源感知、探测和接入机制以及多用户节点协同等问题,并综述了频谱资源分配算法和认知无线网络容量问题的最新研究进展,最后提出用博弈论来研究解决认知无线网络多用户协同问题中的用户自私行为。 Cognitive radio is recognized as the most effective and the most promising technology to solve the problems of the spectrum resource shortage and its dynamic allocation, which existe in the mobile wireless network. Based on the practical application of the cognitive radio in the mobile wireless network, a detailed analysis about the problems existed in the current cognitive radio network is given in this paper, which includes the sensing, detection and access mechanisms of the wireless spectrum and the coordination problem between multi-nodes. After that, summarize the latest development of the wireless spectrum allocation algorithm, and the problem of the cognitive radio network capacity. Finally, it is advised that the game theory can be adopted to study and solve the user＇ s selfish behavior in the coordination problem between multi-nodes of the cognitive radio network.

关 键 词： 认知无线电 频谱分配 网络容量 节点协同
