基于博弈论的多小区OFDMA系统资源分配

立足于限制条件下实现多小区OFDMA系统容量最大或总传输功率最小的优化问题,比较分析了近年来提出的多种基于博弈论的资源分配算法。分析了纳什均衡点存在和唯一的条件,通过引入定价机制或虚拟裁判机制,使得到的解收敛于纳什均衡点。最后,探讨了联合中继节点或MIMO技术的多小区OFDMA系统资源分配算法,该算法能有效提高频谱效率,将成为未来研究的热点。

Survey on resource allocation based on game theory for multi-cell OFDMA system

The paper focuses on realizing the maximum capacity or minimizing the total transmits power under constrains in multi-cell OFDMA system. We analyze and compare various resource distributed algorithms proposed in resent years, which are based on game theory. The existence and uniqueness of Nash equilibrium are analyzed through the introduction of pricing or virtual referee mechanisms to get the solutions converge to Nash equilibrium. In the end, we discuss the distributed algorithms of resource allocat,on in multi-cell OFDMA system joint with relay node or OFDMA MIMO technology, which can improve the spectrum efficiency, and thus it will be the focus of future research.
