摘要 本文以IEEE802.22无线广域网标准为基础,研究了认知无线电环境下MIMO-OFDM系统中分布式无线资源管理问题.基于博弈理论分析,文中首先证明了在全局容量最大化的博弈情况下分布式多用户信道功率分配是Supermodular博弈,并给出了相应的分布式多用户信道功率分配算法,并进一步给出了在认知无线电环境下MIMO- OFDM多用户子载波功率分配问题的解决方法.仿真结果表明,本文算法通过有限的重复博弈,可以有效的提高网络容量. Based on IEEE802.22, the distributed radio resource management problem for MIMO-OFDM system in cognitive radio context is researched in this paper. The multiuser power and channel allocation problem to maximize the total capacity is proved to be a Supermodular game according to the game theory. A corresponding power and channel allocation algorithm is given and extended to the MIMO-OFDM system. Simulation results indicate that our method can achieve greater perforinance improvement in channel capacity with finite repeated game.
