摘　　要：认知无线电的出现是无线通信领域的一次重大变革,它展现了一种全新的频谱管理模式,预示着通信技术进入了一个新时代,同时决定了军事通信的未来技术发展方向。为此,搭建了基于MATLAB的认知无线电台通信仿真模型,该模型针对物理层点对点的通信机制进行了仿真,完成了认知无线电台频谱感知和通信策略优化等功能。通过大量仿真试验,验证了仿真模型的正确性和稳定性,并总结出了影响认知无线电台通信质量的主要因素,从而为认知无线电通信研究提供了一定的理论依据。Cognitive radio is a great change in wireless communication domain, which presents a new frequency management mode and indicates a new era of communication technology. At the same time, it determines the development direction in the domain of military communication. A simulation model of cognitive radio communication based on MATLAB is given in this paper, which simulates the point-to-point communication mechanism and realizes the function of spectrum sensing and optimization of communication strategy. The main factors which influence the communication quality of cognitive radio are summarized by simulation results and the simulation model is validated to he correct and stable. Furthermore, the theoretical basis and evaluating means are provided for the study of communication of cognitive radio.
