基于认知无线电的动态频谱管理理论及相关关键技术研究的中期报告 摘要： 动态频谱管理技术是解决无线电频谱资源短缺的重要手段，而认知无线电技术则是其中重要的一种实现方式。本文针对认知无线电技术中的关键技术挑战和研究方向，提出了一种基于认知无线电的动态频谱管理理论。该理论主要包括四个方面：感知、建模、决策和执行。在感知层面，我们主要研究了信号检测和识别、干扰分析和频谱感知等技术；在建模层面，我们重点考虑了频谱资源建模和网络拓扑建模等问题；在决策层面，我们研究了频谱分配与共享、优化问题和博弈论等相关决策问题；在执行层面，我们研究了频谱资源调度和调制解调等关键技术。最后，我们提出了未来研究的方向和挑战，包括频谱感知的高效化、资源管理的智能化和安全性等问题。 关键词： 动态频谱管理、认知无线电、频谱感知、资源管理、博弈论 Abstract: Dynamic spectrum management technology is an important means to solve the shortage of radio frequency spectrum resources, while cognitive radio technology is an important implementation method. In this paper, we propose a dynamic spectrum management theory based on cognitive radio technology for the key technical challenges and research directions in cognitive radio technology. The theory includes four aspects: perception, modeling, decision-making, and execution. At the perception level, we mainly studied signal detection and recognition, interference analysis and spectrum perception technologies. At the modeling level, we focused on modeling of spectrum resources and network topology. At the decision-making level, we studied decision-making problems related to spectrum allocation and sharing, optimization and game theory. At the execution level, we studied key technologies such as spectrum resource scheduling and modulation/demodulation. Finally, we propose future research directions and challenges, including the high efficiency of spectrum perception, intelligent resource management, and security issues.
