摘要
认知无线电是一种可以感知外界通信环境的智能通信技术，它能够通过对外部环境的理解与学习，实时调整通信网络内部配置，智能地适应外部环境的变化。认知无线电展示了管理复杂网络的新方向，它试图将人工智相关技术引入到网络中，使网络具有自管理、自学习、自优化的能力，从而真正实现网络的可控制、可管理、可信任。同时，它更加注重应用端到端的目标，能明显改善网络QoS
和用户的业务体验。文章从认知无线电的基本概念出发，阐述了认知无线电的基本特征和系统平台结构、发展及研究现状，包括涉及的一些关键技术以及应用领域的相关介绍。

Abstract
As an intelligent communication system, Cognitive radio is possible to perceive the external environment, through which it learns from the environment then implements the adjustment of internal communication network configuration and intelligently adapts to the changes in the external environment. Cognitive radio shows the new direction of managing the complex networks, it attempts to fuse relevant technologies of artificial intelligence into the network, forming a brand new network of self-management, self-learning, self-optimizing , which can realize the reliability of network control, management and trust. At the same time, it focus on the application between goals, which is capable of significantly improving network QoS and user service experience. From the basic concepts of cognitive network, we expounded the basic characteristics of the cognitive radio, system implementation framework, history and development of involving research in this paper, including several key technologies and applications. Keywords: cognitive radio; basic characteristics; key technology; Application
