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
