与传统的频谱管理方式相比，动态频谱接入能够充分利用未被占用的频谱资源，提高频谱利用效率，缓解频谱资源紧张的局面。本文基于双代理结构的认知无线电场景及离散事件系统，提出了一种高效的动态频谱接入方案，并利用连续时间Markov链对该策略建模，计算机仿真结果验证了该方案的有效性及理论计算结果的正确性。

Compared with the traditional spectrum management, dynamic spectrum access can make full use of unoccupied spectrum resources and improve spectrum utilization efficiency. Based on the cognitive radio scene of double brokers and discrete event, an efficient dynamic spectrum access scheme is proposed. By using continuous time Markov chain, Mathematical modeling for this scheme is performed. The results show the effectiveness of the scheme and the correctness of theoretical calculations.
